DO NOT LET SHAUN NEAR YOUR VEHICLE. To save time and money go anywhere else! He puts all the blame on you and takes no responsibility for messing up your vehicle. This is an old yelp account but I am here in California and witnessed Shaun's unprofessional ways to someone very close to me. I found it odd that this shop had 0 google reviews and came upon all these on Yelp. I pre-warned said person about going here and hated that it turned out the way it did after my concerns from all of you here that took the time to leave a review! read more

Went in for a tune for a project car with a Gen 3 coyote that was recently completed. Solid guy, he is open with what he is looking for and open to questions that you may have. Approachable guy that delivered tuning results I expected to get. The two dogs onsite will also provide good vibes! Recommend! read more

You will always be satisfied after visiting AED. The valuable knowledge and expertise that Shaun possesses about coyotes is unbeatable. Before I brought my mustang to Shaun, it would stall and shift unpredictably, but now it shifts even better than a brand new mustang and is more powerful overall. Don't underestimate the importance of investing in quality rather than trying to save money. read more

Had some really basic work done and Drew was patient and professional, entertaining my questions and explaining the process of work done in great detail despite the low dollar nature of the install. When a shop treats you well whether you're spending $1,500 or $15,000, that is something I really respect and value as a customer. read more

I came to Shaun looking for some advice on waking up my stock 2015 Mustang GT. It had Ford's Power Pack 2 tune and I wanted a little more power, with all of the information on the internet it's hard to know what products really meet their claims. Shaun was helpful with guiding me on what parts would make a difference for my build. He has done tons of real world R&D on the aftermarket parts on the market which saved me from just throwing money at the car. He was helpful from start to finish and after a dyno tune my Mustang feels brand new. Id highly recommend him for your Mustang needs. read more

Knowledge is power, mechanical abilities are a gift ...Shaun at AED TUNING possesses these qualities. In turn you come out with an extremely fast running car. I'm extremely satisfied with the quality that went into my build. I highly recommend this business for your car, truck . read more

Drew Wallace is a Mustang Master.. I towed in a 2008 Shelby GT 500 that had several issues From the last owner parking it outside for sometime. Drew also found some janky work from the previous owner. The clutch was not installed correctly and the whipple 3.4 L supercharger had been installed incorrectly . As we got into the repairs Drew was great at keeping me informed and sending me pics of the progress. To me that is excellent service. There were several other issues drew fixed and saved all the old parts for me to see. When I went to pick it up it was a new beast.. Dyno tuned and power tuned.. Shaun did excellent work getting the horses out of it with 91 octane fuel.. read more

I've been running a canned tune on a slightly modified mustang engine. It was terrible, stumbled at very specific rpm ranges and died on me alot. Shaun worked through every one of my problems and even identified another 20 hp I'm leaving in my home built intake. The drive home was amazing! Fixed every source of aggravation with this car. Runs like a swiss watch now. Oh, there's a dog that loves you so bonus there. Give him a try. I'm happy! read more

i was looking to upgrade my shelby for some extra power. in my efforts to understand the pros and cons with my inquiry i found shaun very condescending. if you want to be treated rudely this is you spot. from other reviews his behavior as been noted several times. read more

Was very fast and helpful, helped put on some parts for my car, which went fairly smoothly(the part used to take off the pulley for my car was cheaply made, my fault not his), car runs great and will definitely be back once I put an upgraded blower on my 03 cobra! read more

AED - New pulley, idler - Auto Repair Near Me - Cameron Park, California

Again I called you so many times and never heard back to get it retuned. I've wanted to do a review for sometime on you as customer service is everything and I didn't get that. I'm not going to show up when I live 3 hours away. read more

I have come here multiple times now. They are truly the best experience I have with any shop. I have paid plenty of shops to work on my cars over the years but nothing comes close to how well AED has taken care of me. From being honest, direct, and up front about what it will really cost and what I can do with the budget I have for what I wanted. To following through and not bull shitting about what I would actually be getting. AED is fantastic. Drew, Greg, and Shaun have all helped me out so much with my car and I feel their service is the best I have ever dealt with. Drew has continued to do more than he says he will. He goes way beyond expectations on the upgrades he does and I trust his judgement with my car and what it needs much more then mine. Shaun has not only tuned my car., but then he continues to help me. If I needed some changes in the tune, then he quickly does it and emails me back the new tune. At the track they have both spent a ton of time helping me learn how to launch and drive the car better and better. This place is the absolutely best place to take your mustang/cobra etc. to get high end work done. This is not a used old parts and your car might not last the rest of the month kind of place. If you want it done right the first time, this is where to go. I could not be happier with the service, product, and honestly this is a expensive hobby but every time I feel like I should be paying more. THANK YOU! read more

Shaun is absolutely fantastic. Great communication and knows his shiz. I had issues with my car for about 6 months and after no luck, I finally said eff it and get it tuned by a professional. After talking with him on the phone, he first wanted to make sure the motor itself was okay before we proceed to the dyno. (Other shops not so much) Everything worked out and he was able to help me get my car dialed in. He also got some great numbers IMO, for what we were working with. I would recommend AED to anyone looking for a nice, clean & friendly environment. read more

Had Shaun "the tuna" tune my car was the worst experience. I've had multiple platforms and had been tuned on all of them, so I know what to look for and expect. He could not get my car dialed in, vehicles knock sensors are going crazy on flex tune, but pretty stable on e85. When questioned he either states bad gas or false knock, which is weird to have one tune be decent and the other knocking... read more

I have a 2018 mustang GT and called these guys and wow they are Complete pricks. At least the one guy I had to deal with. I was calling to get an idea of prices for work and the guy WOULD NOT give me any sort of prices. He said he can't give a price on art then went on to brag about himself for 10 minutes. Ended up having to hang up on him so i could stop hearting his annoying ass voice. Go to either paramount in Chico or anywhere else. read more

Absolutely phenomenal service! Shaun is extremely knowledgeable and helpful. He quickly replied to any of my emails and was happy to help. He dyno tuned my 16 5.0 and it's absolutely a blast to drive now! The flex fuel tune works great and he made great power on the car. I wouldn't even consider going anywhere else! Thanks again Shaun read more

Exceptional service and unparalleled work. I took my 2016 Mustang GT to AED after installing a Vortech Supercharger onto my already heavily modified build to have it checked over and tuned. Shaun was simply incredible at both his work and knowledge base. Everytime a small issue was encountered, he was able to immediately diagnose the issue and remedy it. He got my Mustang dialed in perfectly and I'm very happy with the power it puts down. The shop was beautifully organised and clean as well. I'm blown away by the service of AED. read more

Absolutely the worst customer service. Im shocked they are in business. The tuner I talked to today said a turbod cobra using sct software is untunable. Says he would never. If you go to their website it will say otherwise. I'm glad we wasted hours driving towards their shop. Hoping for a knowledgeable tuner. Anyone in the mustang world knows sct software has proven to perform at the highest levels. Not Many complaints. And not that many people resort to a stand alone system. The tuner on the phone said he will never and they never tune turbod cars. Or aftermarket superchargers. On their website it clearly says " we tune with sct software. All boosted applications $550 ° if using stand alone fuel system call for pricing. The tuner I talked to. Or shall I say smart guy is. Shaun Perry 916 715 7569 read more

Supercharger and Hot Rod Cams installed, all with AED tune - March 7, 2014 - (Background about me): I am the pickiest customer ever, with the highest expectations, and ask a million questions about everything. I then do tons of homework before making a move. Background - After hearing on forums how great these guys were I gave them a call. I'm the original owner of an '06 Saleen convertible, with license plates that say I do lemon law. Car dealers are always a bit unsure whether they should work on my car, but AED had no issue and were confident in themselves. My car was a 3v that had all the bark in the looks department but no real bite. For years now I've wanted to get it supercharged and put hot rod cams on it for that old school sound. I wanted it to sound like it was breathing fire when idling and also go like a bat out of hell when you hit the gas. I thought I wanted to go with a KB system. Experience with AED - I called AED and spoke with Drew. After discussing what my goals for the car were he recommended the Whipple HO kit and the FRPP hot rod cams. After tons more questions on my part and a lot of patience by Drew answering every single one of them, including responding to all my follow up emails, I decided to go for it and now couldn't be happier. Not only did they take perfect care of my car - that doesn't have a ding or scratch on it - they did an unreal job with the install and tune. And they kept me posted of their progress while they had my car. Results = Now pop the hood and the install looks clean and sorted like it came that way from the factory. Thank you Drew for guiding me in choosing the right combo for my goals and car, turning it into the perfect machine I always knew it could be. And Thank you Shaun for doing an outstanding job tuning it. I know the cams made it a challenge to tune but you and Drew hung in there and saw it through even when it required extra time and a few extra runs and test drives to get it perfectly right. Also, thank you guys for coming in early that Friday morning to get it done a day early, I really appreciate it. I am so grateful to Drew, Shaun, and everyone at AED who turned my dream car into a reality! I highly recommend AED for any Mustang engine mods and tune! I will be back for sure when I'm ready for more mods. Update- 4/4/14 - Being super detail oriented after further inspecting my car I noticed what I believed to be a bolt touching a hose, which is not a big deal for anybody else but me. I called Drew and he said no problem bring it back. I did and Greg at the shop was super nice about it, got my car right in and made some small adjustments, and reinstalled the bolt I was worried about. He was totally cool about it and despite it not being a real issue still took care of it because I asked. Thank you Greg, I appreciate you and everyone at AED! Update 6/11/14 - The car developed an unusual noise that sounded like a fan belt squeak when cold that would go away within about 5 minutes. I emailed Drew and he said bring it in as soon as I'm able, that he'd check it out. Drew figured it all out right away, switched out a failed pulley and replaced the belt. No charge, super fast service, and they even got the car washed. I'm extremely grateful. They didn't have to do anything, yet they took care of it all and went the extra mile too. They again confirmed by their actions that I picked the right shop to work on my car! read more

All I can say is awesome so far. Shaun seems to have an unparalleled knowledge of Mustang engines particularly the s550 platform. He got me switched over to a nice safe higher HP E85 tune vs the Ford performance tune(Performance Pack 2) I had that seemed to run a potentially dangerous level of ignition timing. The level of R/D Shaun has done on the s550 and I'm sure other Mustang platforms appears to be massive and extensive allowing him to give very good advice as long as your willing to listen :) Highly recommend you go see him if your thinking of upgrading/tuning/engine building for your mustang as his advice for a street car(daily driver) will be much different from a road course car/track as well so good to understand that as well due to some limitations of the Coyote engine. read more

I've continued to have my GT500 modded and tuned by Drew, Shaun, and their team, and many many upgrades later, I continue to be very impressed with their technical skills, dedication to their craft, and perhaps most importantly, their integrity and commitment to their clients. They will take care of you and your car, and they will make your car go (and stop) FAST. There is no better performance shop around. I would not take my car anywhere else, period. read more

AED is one of the best shops I've been to I highly recommend anyone to go there. Shawn is a very nice guy he will help you out.

Ok LostBrain, check this out. I read a lot of positive things about AED on forums and spoke with several people who had personal experience with them. I decided to have them tune my 2004 Whippled Cobra because the car came from another state and I wanted to make sure the tune was legit. Turns out, it was "okay" but definitely not up to par. Shaun actually offered me two options, one of which was about HALF the cost of the second. I opted for the additional work because it just made sense to get the performance tune done at the same time and save money in the long run. They were professional, patient, and very knowledgeable. I stayed and watched throughout the entire process. Let me tell you, I was impressed by the way Shaun paid attention to detail. He explained every aspect of the tuning process as he went along. It was like getting a free mini course in tuning. I have been wrenching on cars for over 20 years and have done just about every type of repair. However, with a modified muscle car, one has to know their limits, hence trusting my car with these folks. They had some really nice cars and trucks on the property and some out-of-state cars as well. Hmmm... now why would somebody spend their time, money, and hassle to ship their car to a tuner in a different state? Maybe they are just other "cash cows" looking for a better milk machine? *scratches head* Idiots get what they pay for... if you want to save money, let Wal-mart work on your car, then start shopping for a new engine right away ;) If you want things done right, quit your bitching and fork over the much justified cost of confidence...

The guys at AED are bad ass ,definitely will be bringing anything I buy in the future to these guys and would highly recommend.. Shaun is the man when it comes to tuning. Thanks again AED for getting me dialed in , will definitely be a repeat customer! read more

Where to start! I have a 2012 GT500. The S/C was just upgraded with a Whipple 2.9L With a 3" pulley. I took the car to them due to the issues I was having with drivability. Well after AED got their hands on the car and worked some magic well let's just say dddaaammm. Went from a 3" pulley to a 3.25" and added 53hp at the wheel. Now if you read this and understand the dynamics it will show just how well they know what they are doing. Awesome work! Drew/Shaun read more

I contacted AED to tune my paxton mustang, I was asking questions so I would know what to expect when tuning and shaun was not professional, very impatient, bad customer service so before even purchasing a tune i turned away so I will now be doing business here. read more

If you want custom work done right this is the shop. I took in a stock 2010 GT500 and Drew worked with me on a supercharger, suspension and transmission upgrade. I went with the Whipple 750 HP kit, but Drew made several additional recommendations that made more horsepower but was also safer for the engine. He made a number of suspension and cooling recommendations at my request, as well as new clutch (to handle the HP), shifter (which fixed the factory grind), as well as a few other tweaks. It took a long time to get in to actually get the work done but was worth the wait. First off, when you get to the shop it is completely organized and you could eat off the floor. Both Drew the installer, and Shaun the tuner were super busy, but willing to take the time to answer all my questions, and I had a lot as it was a bunch of money to do it all and do it right. I had a lot of followup questions by phone and email after doing research on his recommendations, and Drew answered them all very quickly. He knows what he's doing and can dial in your request without spending money for things you don't need or won't get you closer to whatever goal you had, despite the fact he could make more money by installing them. In other words he talked me out of things I thought I wanted because it didn't help in my HP quest. Honest is nice. The car came out absolutely perfect, on schedule and on budget, despite all the work there were no surprises and it runs flawless. I'm a perfectionist and I checked over everything and even the littlest detail was perfect and best of all he made all the wiring look OEM. What really impressed me is when I came to pick up the car it came completely washed and detailed. I showed up with a pair of OEM rear rims with cheater slicks and felt bad asking Drew to put them on as they were really busy but he did, but also put Armor All on the new rear tires so they would match the fronts he had just detailed. Like I said he's a perfectionist, and as he was putting them on I also noticed him doing it by hand with a torque wrench, not a air wrench like they do it everywhere else. I couldn't recommend this shop and these two guys any higher. read more

Pretty small of you to attack and insult someones review there Johnny boy. Its ok to be a fan boy but don't insult others experience. Not everyone has a good experience like the 2012 n/a gt that blew less then a day after they tuned it. Blown motor and aed not even trying to help the customer and left him to hang... Review are for everyone's experiences not just yours fool. read more

Clean shop, good work, and best place to go for performance mods to Mustangs. Keep up the good work Shaun and Drew!

Just dropped my mustang off at AED for some exhaust work and to get a supercharger installed. I must say, the shop is very impressive...probably one of the nicest I've been to in Northern California. Definitely a great spot for high end work. Drew and Shaun are great!!! read more

Been in contact with Shawn for over a month about tuning my fox body. After a few phone calls and some prep work, I finally made it in for the tune. He was extremely knowledgable and professional. Although I have to go back for some final touches (due to not having the proper materials on my end) I am confident my car will be on kill when he's done with it. I would recommend this shop to anyone. read more

Tuned my twin turbo mustang and did not set up the over boost correctly after installing it. I told him to make sure and double check because I saw it was set way higher than it should be (24 pounds instead of the 14 at max it should be set on). We did some waste gate pulls then got into higher boost. Due to the overboost being set wrong he blew my newly built coyote on the dyno and didnt offer any help or take responsibility for his mistake. He blamed it on being "car stuff" and that for tuning that anything can happen and that I knew the risks. My $15k motor is being torn apart by a real reputable shop now and I will not be heading back. I advise dont take expensive products or vehicles you care about anywhere near AED. They might do a good job for some but they made a 15,000 dollar mistake and blamed it on "car stuff." I would be suing but for these situations it is very hard to prove. Be wary read more

Was very u happy with shaun's customer service skills. I have been emailing him about tuning car and sent him a detailed list of the mods done to my car and when i showed up on tune day he had no clue what was done to the car and asked me a bunch of questions. He might be a great tuner but he lacks customer service skills and did not let me experience the tuning process for the car was tuned without be being there and was not able to record any of the pulls it seems to me like he runs a business in a money trap way only going after the money and not a satisfied customer would not recommend his services if you want to experience the tuning process of your car. read more

Awesome experience. Car is running stronger and smoother. Shaun definitely knows his stuff and even takes the time to explain everything. My daughter and wife had fun as well. I highly recommend AED and will be back again for more. read more

I heard a lot about AED and Shaun being a wizard with tunes, so I decided it was time to contact him and get my car running right. Not even 10 minutes after sending an email to him, he responded and answered all of my questions that I had. Long story short, booked the appointment, and had my car running WAY better and smoother than it ever had with a Bama tune. I can't say enough good things about this guy and his work!! read more

Shaun dialed in the tune on my coyote mustang. What a difference in power and drivability. I will be back in the future for sure. Quality and customer service is #1 for Shaun and his team. This shop don't F#%* around! read more

AED - Auto Repair Near Me - Cameron Park, California

I first contacted Shaun with problems I had with a Power Pack 2 I was having issues with. He quickly replied to my email not only offering to help but shared experiences he has had with Ford Performance Tunes. I set up a Dyno Tune Date and he got some good power out of my car and all issues where fixed. I then desired to overhaul my car completely, Shaun advised me on mods and gains I will see with a flex fuel tune.. to my surprise after modifying the car per his recommendation he hit the exact number he had estimated on the dyno which was really impressive. That being said, Shaun is the guy when it comes down to modifying and tuning your coyote. His knowledge base and quality of work are superb. I will continue to contact Shaun before any mods are done to my car to make sure I am getting my moneys worth and will always run an AED tune. Thanks Shaun read more

If you have a Mustang, and you want the most honest and talented hands taking care of your car, go see Shaun at AED. Period. End of story. I shopped around and spoke with most of the well known tuners prior to trusting my 2019 Shelby GT350 with Shaun. I chose him because he took the time to get to know me and my car prior to making any suggestions about how to best approach hunting down any and all extra HP possible on my car, and he did so while always guiding me towards the safest way to do so for my particular car. I was ready to spend big bucks on applications that would have added tremendous power and made him a lot more money, but he ultimately refused to do it as it wasn't in the best interest of the car, the long term health of the motor or me given what I told him I wanted to do - I wanted to be the fastest GT350 possible for daily driving, hard spirited driving on the weekends, an occasional ass-kicking off the line from a stop light and a few annual trips to the track. Shaun took the time to deal with me and all of my questions over the course of a few months of talking about it while educating me and managing my expectations. It has been a great experience and my car is dialed in on 91 pump, 100 race and E85. Very dialed in. See you at a stop light.... read more

Once again, the guys at AED provided world class service... To be honest, they are the main reason I purchased another mustang. I purchased a clean 03 cobra and scheduled time with Drew to perform exhaust work and install a few cooling mods before Sean worked his magic on the Dyno. I can't say enough great things about the quality of work Drew performs, he is a perfectionist with everything he touches on my car; he even went over and above and realigned my entire exhaust system to get it perfect! He knows cobras and all mustangs better then anyone, I will be a customer for life! And Shaun is an absolute tuning whizz and is a stand up guy too; my car came with an SCT iTSX tuner and I was ready to purchase a new Tuner, but he worked with me and spent the time to get the tune perfect with the iTSX that came with car and saved me $400. Drew and Shaun are great guys and wont try to oversell anything, which is rare nowadays. They are extremely busy, so be patient, it's well worth the wait! read more
