Amazing experience. I'm not the biggest car guy but wanted to get some mods added to my 2023 WRX. Alfred walked me through the process. The upgrade options to look at. The pricing. Everything. After picking up my car. Oh man oh man. Pure bliss. Drives like a dream. The tuning on it is perfect but I will say. I'll be coming back for some more Again, amazing service and all around experience. 7/5 stars if I could. read more

This review is long overdue but avoid coming here at all costs. Went to get a reverse synchro replaced, when I picked up my Evo8 they put a rev limiter to "help break in the transmission." When asked to remove it he said it he couldn't put my original map back and it needs to be retuned. Long story short, I fell for the positive reviews, along with thinking he and his wife were good people, so I let him "retune" my car which was a mistake since he ended up destroying my motor. I got my car back barely running and when I tried to go back for answers I was avoided at all costs. Take this as a warning and just don't. Don't let the positive reviews fool you. (if he or she replies to this saying they have no record of me being there, it's because they threw the record away.) Again just don't. read more

Went to Tuning Technologies and everything went fabulously. Alfred, Jen and the rest of the guys are really nice ! They have a lounge where you can relax at as well! overall i'm super happy with the tune for my WRX and will be back if anything rises ! read more

Alfred, Jen, and the TT team are very professional and I'm very satisfied with their work. I was new to Subarus and they always answered my questions and provided information as well for what my goals and options are for my car. It's been 4 months since my WRX VB was tuned and I love the way it runs. I definitely recommend them. read more

Great service and recommendations for your car. Highly recommend them to others within the community.

My Evo had a ton of issues when i first it bought a year and half ago at 150k miles, I'm grateful to have found TT because they took care of me and my car while educating me about it at the same time as I'm still new to the Evo platform, The team they have there was very good and they told the estimate up front and had a copy of via email. Its been about 2 months since I picked up my car from TT, its been amazing and makes good power. I'm extremely happy with my Experience. read more

Got my car tune there two time the money is worth it Great customer service if you have any questions they will help you. The only place I will get my car tune. Great waiting room. if you need parts, they will order it for you. 10/10 read more

Hey ladies and gentlemen, I just had to leave a review, today I came in for a scheduled tune for my Evo 10 had some issues with my vacuum lines usually some shops charge,but the guys here did a good gesture by fixing my vacuum lines and didn't even charge me, I mean, Man, the customer service and the technicians in the back are real respectful!!! And I would like to also add that I brought my two kids with me and in the lobby room, they have toys for the kids to play with while they were tuning my vehicle they brought complementary water and anything else I My kids were also able to use the restroom when they needed to go. These guys went over and beyond. For the why I'm definitely giving this a shout out to the tuner Alfred, I appreciate information and education me pertaining to my vehicle,,, and also had some parts there in house to keep my car from catching fire!!!! For a very reasonable price!!!! I just want to thank the whole team Alfred and Jen and the technician in the back for the love and care for your customers!!!!!!! read more

If you're looking for an honest, upfront tuning/mechanic shop, go here. Alfred and Jennifer were so friendly, kind and helpful. I bought a wrx off of them with a new motor, and once the motor was broken in, I had Alfred tune it since it had a downpipe from a previous owner already on the car. Alfred was able to make my car run beautifully, smooth and with plenty of power. Alfred also recommended putting on a boost controller as well, and I agreed since I wanted a more reliable tune / daily driver. If I do any more engine mods in the future, I will be taking the car back to them. Thanks you guys !! read more

Service was amazing. Alfred kept me in the loop through the entire tuning process of my Evo X. His knowledge on the car was awesome, which definitely made me feel extremely comfortable with his work. Jennifer was stellar, great customer service! Even offered me food from their holiday celebration! Had that great family feel of enthusiast helping other enthusiast! read more

Def recommend anyone looking for a tuner. My wrx feels so smooth after Alfred tuned it this past Saturday. Expect to take about 4-5 hours, but they do have a chill room where you can watch Netflix or play PS4. If your WRX or evo needs a tune, just call them up and speak with Jenn to setup an appointment. read more

This is my 2nd time coming here. Best tuner. Wouldn't recommend anyone else. Especially if you live in the IE. I recommend coming here only! Alfred and Jenn are amazing people! Knowledgeable and very helpful. I came here the first time to get a tune after installing a downpipe. They did an amazing job so I decided to come back again to get a flex fuel tune and guess what? They still did an amazing job. My car feels amazing. They even fixed that annoying stumble that all late models STi's have. They also did some maintenance on my car and I'm happy as they can be with their expertise and commitment to make sure my car comes out 100%. I will be definitely coming back again for a bigger turbo and equal length headers to be installed. Couldn't be happier with this place. Amazing people. Amazing talent. Amazing outcomes on your car needs. Thank you so much Alfred and Jen. I appreciate all the hard work read more

1000% recommend this shop for installs and tuning. The hospitality is amazing felt at home they have an awesome lounge that you're able to watch YouTube and also see your car being tuned. Alfred is a great tuner and knows what he is doing. Subie sounds and runs great. Can't wait to go E85 and come back. read more

Alfred and Jen are so friendly and their customer service is top notch. They even have a cute mascot named Wrigley. I drive all the way from Santa Clarita because I trust in Alfred's genius tuning skills and his experience in tuning Evos. Not only does he cater to your needs he points out potential problems in the future. I highly recommend Alfred and everyone at Tuning Technologies as your Evo tuner, they are an amazing tuner that can keep your Evo running for years to come. read more

Came in for a tune and was happy with the service I got and the power that I made! I liked how Alfred sat down and spoke with me on everything he was going to do.

This place is absolutely amazing. I have a Subaru WRX STI and am very impressed with how knowledgeable the owner is. Bring your car here before even thinking about anywhere else, you will not be disappointed. Excellent place! read more

I reached out to TT amongst other SoCal tuners back in August 2020. Alfred was the only one who responded with an actual interest in the build. At first it was via Yelp, then email, then on the phone. I made the actual dyno appointment in October 2020 because I had to pull the motor for a rear main seal and separator plate leak. The wait time was about 7 weeks to December 22. When December 22 came around I had to decline the appointment due to the covid spike after Thanksgiving. Jen and Alfred understood, and rescheduled my appointment to February 3, 2021. Dyno day was nerve-racking as usual but after ironing out some Accessport connectivity issues the tuning began. A week has passed and I got some decent seat time in today. The car runs great. I even got a follow up email from Alfred which shows he cares for his patrons, not just their wallets. Hard to find these days. I went with Alfred as I remember reading about him in Sport Compact Car magazine in the mid 2000s. read more

ALL 5 STARS!! Alfred and Jenn are AMAZING! By far the best customer service experience I think I have ever had. There is a reason they are backed up for tunes, Alfred takes his time with every tune and both of them offer nothing but genuine kindness, pure knowledge, and just all around customer satisfaction! Alfred tuned my 06 Sti to the perfect point for both daily driving and bullying mustangs. Its awesome! If you have any questions im willing to bet one of them has the answer! And if they don't, they know EXACTLY where to find it. Great shop, great builds, and even Greater people. I cant wait to get retuned after a couple more supporting mods for that 450 mark If you're looking for a tuner and you've stumbled across TuningTech look no further, book your appointment and be patient. Cause its 100% worth it. Thank you guys WILL BE BACK! read more

Alfred and Jen, and the rest of the team at Tuning Technologies are some of the most dedicated and passionate people in this business. With what you pay for regular car service, you will not find better! Whatever tune or problem you have with your car, Alfred will make sure your car leaves their garage with exactly what you want. Whatever problem and question you have about their service, Jen will ensure that all concerns are put aside. For me specifically, my car had a very unique problem that all other tuning shops refused to fix or solve. Tuning Technologies, however, had all the confidence and guaranteed a solution without hesitation the moment I called them. Upon arrival, they did not disappoint, and instead went above and beyond by sitting me down and making me a part of their process. Overall, these are some of the nicest, honest, genuine people and their service definitely lives up to the same degree. read more

great experience overall. I'm impressed and satisfied with the numbers they were able to get. Thank you again Alfred and Jen. I'll recommend you guys to more subie owners read more

10/10 Experience. Jen and Alfred are very friendly and will guide you through the entire process from start to finish. I took my Evo X for it's first tune and I couldn't be happier with the results. Will return in the future for another tune with them. Highly recommend! read more

This shop is awesome. I was looking for a shop to install a higher final drive gear in my 350z. I hit up 3 other shops and they all said no due to the complexity. Tuning Tech took on this specialty job and nailed it. I'm so happy with the craftsmanship they put in there work. The customer service is awesome. They are on time and estimated completion date was accurate. Can't wait to do business with them again. read more

I'm sure everyone who knows "cars" and imports already have their favorite import shop, but if you don't or want to find a really good shop with an all-wheel dyno and great service, I think this is definitely the place! I moved here 5 months ago with a very "jacked up" Subaru WRX, clutch was totally gone and everything was loose as a goose in the engine. I found these Evo (Mitsubishi Lancer Evolution) experts through a co-worker at work who owns a mean Evo. He said that this place was by FAR the best in SoCal, so I had to give them a try. I made an appointment for that week to fix my clutch (which is almost impossible in LA) and showed up at the shop and found myself surrounded by about 15 Evos(which is really intimadating if you know about the STI vs. Evo rivalry), but they were all very nice and excited to actually branch out to fix other cars. They have a new shop with two garages and a new all-wheel dyno. I was welcomed by Jenn and Paul who were extremely nice and got to know them pretty fast. They fixed my clutch and resurfaced my clutch with ease and I am very glad I went to them. Great customer service and they did an awesome job. Only bad thing is they are kinda far outside LA. read more

Tuning technologies is a very reliable and friendly business ran by extraordinary people. Alfred is the tuner and he took the time to answer every question I had and even talked about other things beside the car. My 15 wrx was tuned at 11 am and finished at 2:30-3:00 pm. I had a clear view of my car getting tuned and loved watching it on the dyno w Alfred. Jen is just as awesome. She runs the front end of the business and as great as they come. She communicates well from the time you make your appointment and a week before your appointment. The waiting room is one of the best waiting rooms I've been in. Both Alfred and Jen are great running their business and even the techs do a fantastic job w all the cars. I highly recommend going to this tuner for your needs if you are in the inland empire. Thanks for the lunch Jen ! This business is very covid compliant. read more

Absolutely amazing service both tuning and customer support. Answered all my calls and answered any questions I had. Tuned my 21 wrx and did an amazing job, will be coming back :) read more

Alfred is THE guy to go to for your EVO. I came in with so many issues and questions-- he answered all of them with patience and accuracy; furthermore, was never demeaning or an a**hole like most shops you run into. That was one thing that made it for me: everybody is so knowledgable (and nice) here, you KNOW your car will come out better than when you brought it in. Alfred took the whole day repairing my car, literally 8am-5pm, to make sure I was able to get home that day. Seriously a hard worker and really cares about your car. Highly recommend read more

I have been going to TT for over 14 years. They have done an amazing job taking my stock evo 9 mr and transforming it into a reliable 500whp beast that I can take to the track. Their prices are fair and they are very skilled and knowledgeable of their trade. When they say something needs to be changed out or a certain setup won't work then it's usually true. Definitely the shop to go to. read more

I won't go anywhere else, I got a brand new Motor and a upgraded turbo running better than ever on a tune by Alfred. I recommend this shop to my friends whenever they are looking for a good tune. read more

This place is the perfect place for getting an Evo tuned in SoCal. Alfred, the owner, is the man. He's super smart but more importantly he cares about YOUR build. He knows how to build an Evo, but he also knows everyone's cars are different and he'll do everything in his power to make your car YOURS. Everyone here is very smart and most of them are evo owners themselves. I took my '15 FE here to get dyno'd and they worked on it tirelessly until the tune was done. I will come back here for any future help I need with my Evo. read more

Took my 08 g37 here a few years ago. I barely made an account recently so I thought I would post a review. Alfred is super nice and so is the lady that works in the front office sorry I forgot her name. They're both professional and courteous. My car was Dyno tuned with uprev, Alfred show me the results sheets it's putting down 305 horsepower to the wheels with just headers and a CAI. The tuning session took a little longer than I had expected but that's probably just because he wanted to get things just right. It was a little intimidating taking my humble car with simple bolt ons to a shop that is loaded with fully built evos and STIs. but I felt as if Alfred gave my car just as much love as those other ones. Thanks tuning tech for taking care of me I'll be back when I have the money to do some big jobs! read more

Before coming here to get tuned, I set up an appointment with jen. very friendly, helpful and professional. I then spoke with Alfred, shop owner/tuner Over the phone, he helped me by asking me about my car and what parts he recommends me getting after I had upgraded my turbo so that everything thing would run smoothly When I went to get tuned. Alfred and his team go over your vehicle and preference on how you want your car to run. Throughout the process he updates you On everything as he tunes. Fixed major problems with my previous tune and took his time to work out all the bugs. I couldn't be happier with my experience at tuning tech. read more

Alfred at Tuning Technologies is the man. I bought an Evo X that had a bunch of aftermarket parts installed & it wasn't running the smoothest. Alfred explained to me the ins and outs of the car, gave me a parts list of everything done to the engine and gave me a solid 91 octane tune (365hp/309tq to the wheels) I feel very confident driving the car now and I'm definitely looking forward to my E85 tune from Tuning Technologies! read more

So all around amazing experience!!! Customer service A++ and the tune turned out amazing !!! Did I fee small things to my car in take inner cooler and down pipe !!! Tuning technologies was able to get 40+ hp out of it and my car has never ran as good as it does now !!! Thank you guys and I will tell everyone about you !! read more

I bought some coilovers not from here but this place is an authorized dealer of the brand I bought. So I figured that I could take it in and maybe they could help me adjust them since I really don't know what I'm doing and it's not riding the way I feel that it should. Anyways I get on the phone with them and I ask if they can help, he asks where I bought them and he told me to call them instead. I told him I haven't tried calling them yet. He asked if I had called the manufacturer. I told him yes but I don't understand what they tell me to do. Again I am new to this type of suspension. He said to just call one of them and they should help you and good luck. Now according to yelp this place is an auto shop and I don't understand why they couldn't help me. I'm not asking for free labor. All he had to say is bring it in we charge this much an hour and I would have been there. Don't expect help from here unless you buy products from here. At least thats how they made me feel. Hopefully the manufacturer doesn't try to send me there cause if they do, they will be hearing a mouthful from me. read more

I have an Evo9 that I want to make a fun street car. I was stuck between going to a local tuner such as ktm or 5150 but Tuning Technologies had tuned 3 of my buddies evos and Sti's and from being there before and driving these vehicles that they have tuned I said screw it I'll make the drive out there(50 miles out to them) Glad I did, customer service is amazing. Alfred is a very talented man, tuned my evo 9 and most importantly talked to me and gave me advice on what I wanted to do to the car for the future. Besides having to wait a few weeks for my appointment, it's totally worth it, I mean come on if they are booked that much, that should speak for itself. I highly recommend Tuning Technologies. read more
