I just had my GtR back. They did an amazing job. It was an out of state purchase and had a lot of parts that needed replacing. Emissions, engine management, tires and down to the car getting a good detail. Ozzie is the man. He will help pull it all together. James was always helpful in steering me in the right direction with this car. So whether you need a new set of tires or a full rebuild don't hesitate to call ACG read more

Ozzy and the team at ACG are top-notch! Got me in quick when I needed tires and a balance done in a pinch. Fast, professional, and effective service -- they had me taken care of right away. Highly recommend! Will Return for future work and performance upgrades. Side note : Drive a M240i BMW 2021 read more

I've been taking my car here for over 2 years and these guys are the best. James, Ozzy, Scott, B, and the rest of the crew all are incredible. From modifications, to bodywork, these guys can do it. They've saved me headaches numerous times. Don't hesitate to call these guys! Thank you! read more

If you're in need of a simple oil change or a complete teardown and rebuild on a motor. ACG has been incredible to me over the decade that I've been working with them. They work on all my family cars including my race car. James, the owner is very honest and will tell you what exactly is going on with your car instead of trying to sell you on things you don't need. He's one of the most educated people that I know in the community. Thank you ACG Automotive for everything you do - you guys are true first class people. read more

I'm new to the Dyno Tune game but read reviews and thought ACG Auto would be a good place to go. I took my 2014 M6 w/ Competition Package in today to have them look at it and do a Dyno Tune. I have a new engine installed and it only has 7k miles. It was running a little rough when I stomped on it. They ran some tests found the battery was not registered, found the positive terminal loose, tightened it and cleared the faults. This was why the car was missing because of the electrical power issue. I was planning on having a Diagnostic Check and Dyno Tune done to my car as well. I learned that this is not how it is done. There are some things that must be done first in order for ACG Auto to Dyno Tune you car; All New NGK Laser Iridium Plugs $147, Install them $375, BOOTMOD3 S63TU - BMW-F13 Tune $895 and Real Time Tune $250+ for a Grand Total: $1,747.97 I will likely take it back but learned how this process works and figured it might help someone else who is not as well educated on the Dyno Tune process like me. read more

James at ACG let my challenger Hellcat sit at the dodge dealership for an entire month straight in the sun. My clear-bra shrunk, battery died and he pretended as though nothing was wrong at all. Thankfully I went to the dealership myself and had to do his work for him, getting all required information for the transmission warranty, convince them to install a new battery etc. Had I not followed up, there is no telling how long it would have sat if I wasn't proactive. My car was under his supervision for an entire YEAR just for a transmission install. There we're issues with dealing with the warranty so but I had to do all the leg work even though the warranty contact would only talk to a shop owner which he was obviously aware of. About 10 months into my car being at ACG, I decided to just buy a build trans instead which they installed but there were still issues. My battery died AGAIN after getting my car back a year later so I had to buy a new one. I called everyday for a week, sent emails to Marco and videos of the power draw issue. I troubleshooted for hours pulling fuses to reset the dash, updating firmware etc. It's as though he intentionally makes it difficult to get in touch with him. I had to walk in the back bay doors and tap him on the shoulder while he was on the dyno just to get a word with him. The interesting part is he knew there was a power draw because he said, "Yea I noticed your car had trouble going to sleep". He was aware of this issue the entire time and agreed with me that when the battery died, it reset the steering wheel voltage monitoring settings, drawing power. He declined paying for the battery that HE was at fault for letting die. At that point I realized I would never take my car back to this shop again. read more

James is incredibly knowledgeable, asks the right questions and offers competitive pricing. Will be a long time customer!

i have been working with ACG for a few weeks now on a new (actually old..2012 E92 BMW). I am in the process of upgrading the performance of the car through some modifications as well as addressing some deferred maintenance and other unexpected issues. James and his team have been very on point through out the process helping me find the most reasonable and cost effective solutions. Their level of expertise, attention to detail and genuine concern for maximizing value based on my particular needs is truly appreciated. read more

ACG Automotive is a great place for both performance-minded and maintenance individuals. James is very thorough when explaining options and solutions for a specific requests. Performance shops are a dime a dozen in southern California but ACG Automotive sits among the upper crust. Boosted applications are his specialty but I've also had regular maintenance/repair done here as well. The techs were meticulous in their installations and were able to point out sloppy work that was performed by a different shop here in San Diego. (Rear diffuser was not bolted back properly and the bracket was bent by another shop...) They were able to straighten out the bracket and thread it back into position, saving the bracket and a headache. They could have charged me to replace it but took the ethical route and explained to me what was happening / might happen if they attempted to repair it. If you have an Audi, you're in luck because several of the techs here have extensive experience with them. Michelin tire installs went well and if it wasn't for the perceptive eye of their techs (once again), a bad powder coating job from another shop would have gone unnoticed! Communication is important and James isn't afraid to lay things out / say things as they are. As a businessman, I appreciate and respect this. read more

Came at 10am for the appointment. The work to be done should not take too long. We went out to grab sth to eat. Came back to the store hoping the car is ready after 3 hours: the car is still untouched. One guy is telling me I can relax and wait. Does this guy know we arrived here three hours ago? How can I relax longer? I am furious. This is my husband's choice. He seems fine. Biggest mistake I followed him. I don't care how their work is. My time is precious. read more

ACG Automotive is a great place to take your ride. They work on Ferrari's but then you bring in your Ford Expedition and they work on it the same. All of my vehicles will be going there even if it's for a simple oil change. read more

My Infiniti blew its head gasket and after replacing my head gasket, I had to set my VVEL or else my car would run on limp mode. A lot of the auto shops I called didn't have the program to set my VVEL and the dealership would have charged me a lot for the service. Fortunately, ACG has the program so I towed my car there, got my VVEL set, and drove my car out fine once that was done. James and his team are professional and easy to work with. I would recommend this shop. read more

These guys are idiots. I gave them the benefit of the doubt soooo many times. Leaving a rag in my shock tower, not tightening the lugs on my wheels, but yesterday we found a tool they left right next to the downpipes they installed on M5 last fall. Unbelievable. If anyone suggests ACG as a shop to go to, avoid. You go in there and it feels like the movie Boiler Room. read more

I went with James and team at ACG to do a performance and cosmetic project on my AMG C63 coupe. Project included full headers, transmission, Weistec ecu/tcu tune, suspension and extensive carbon fiber inside and out. James went above and beyond to ensure that the end result was exactly what I was looking for. Would definitely recommend ACG to anyone looking for top notch auto work. read more

From simple maintenance to huge builds. My gtr started as a simple stock Gtr then full bolt on e85. But the power bug bit after experiencing my first 1/2 mile event. With only 5 days till the next event I asked the shop if it was possible to do a full motor build and install aftermarket turbos. They made it happen and ran my car without any issues at the event. All within the same year my car is now a 1400hp monster that i drive everyday with no issues. If you follow their advice with your build and not cheap out the outcome becomes exactly what you want. If I ever had a question or issue it would quickly get resolved all I had to do was say something. I will continue bring my vehicles to ACG and my next power level goal is 2000hp this year. From GTRs to Rolls Royce Ghost even to the simple Honda Civic ACG does it all! read more

The parking lot is like a mini-autoshow with heavily modified supercars. The people at ACG know exactly what they're doing when it comes to modifying or fixing expensive cars. I took the GT-R here today to get new tires and in the process saw about 4 or 5 GT-Rs, a Lamborghini, and a gt3. It's just simply amazing The young lady at the front desk is very friendly! I don't think she has a single snobby bone in her body. I haven't met James yet, but the guys from the GTRlife forum vouch for his expertise, kindness and professionalism. My gf has been in communication with him setting this appointment up and says he's a really nice and easy guy to talk to. I got a great price on the tires on my gf's dream car and the shop is in tip top shape so I trust that they know exactly what they're doing. read more

Great work done by these guys on my 2014 is 250 . Rs r down springs and takeda intake . If the owner of the shop or manager reads this I hope next time they are a lil more accurate on the time they give u for the work to b done . But overall very happy with their work :) read more

Called for a quote was very rudely told I needed to email pics. I decided to just go to the shop so they could see in person what I needed fixed. While James was looking at the issue and giving us his estimate and a client drove up and James just walked away, he didn't excuse himself he just walked away. Regardless of the lack of professionalism and rude attitude I had been receiving I was willing to get my work done at this shop because of the stellar reviews on yelp about their work. He came back from speaking to his client and seemed rushed to get done with speaking to me so he could get back to his client. He told me to email him so he could provide me with a full quote, I emailed him that same day and he never emailed me back. Clearly he doesn't care to acquire new clients. read more

James and his team are fantastic. I've been bringing my MKIV GTI with a 12V VR6 motor to these guys for ECU flashing and (just recently) some dyno pulls. While I don't represent one of their more serious / high end customers they've always taken care of me and treated me with the utmost respect. I highly recommend having ACG at the top of your list for performance related automotive work. read more

Took my Tesla here for some suspension work and everything turned out perfect. Girard is an awesome guy and communicates everything clearly.

I have a 2015 Nissan GT-R. I came here for a simple job. To replace the aftermarket air intakes for the stock ones. The aftermarket intakes were throwing a engine code on the dash. These guys did a thorough job for an exceptionally low price. The Nissan dealership across the street charged DOUBLE just to reset the code - the code came back 2 days later. These guys replaced the intakes and reset it for HALF the cost. These guys rock. read more

Been taking my cars here for the past 3 years and never have I ever been disappointed. Open, honest and friendly. The whole staff is knowledgeable on all aspects of the automotive industry. Beyond that their facility is state of the art, organized and clean. I've had my 458 Italia, GTR and most recently Wrangler modded there and they continue to impress. Thanks James, Sean, Tal, Asan and Wes!!! read more

I learned about ACG through some performance sites and went to them for some tuning on my car. Tal was great to work with and provided great options and recommendations. Their staff are experts and I was glad to learn that that my car was taken care of by a Mercedes trained technician. They provided great customer service and even took care of an exhaust fitment issue at no cost to me. I really felt as if they valued my business even though my mods were mild compared with the exotics they had in the shop. Their shop was very impressive and organized. They also have a Mustang dyno on site. I will definitely be coming down to ACG for all my tuning needs! read more

Just wanted to publicly acknowledge and thank James @ ACG for his assistance. In trying to set clutch capacities and touchpoints on my GTR last evening, I managed to get the DCT computer angry with me....night before I'm supposed to head to a track event. James was gracious enough to respond to my call for help, despite it being after hours, and suggested I stop into his shop the next morning to make sure I have a better understanding of how to use the ECU-teck module. This morning he gave me an "ECU-tek for dummies" lesson and sent me on my way. Incredibly nice of him and I'll certainly remember this when the GTR needs TLC down the road. Thanks James @ ACG. read more

I had my Jeep's front windows tinted here and they did a great job. Real quality work, timely, and Sean is very friendly. I had them match the front percentage to the back windows, however, I read somewhere that it might be a good idea to get the front windows 5% darker than the back ones, since the factory standard back windows have a slightly different 'tone' and the light coming through the front windshield already makes the front windows appear slightly lighter. As it is though, the windows look good but you can see a subtle difference if you are looking for it. I will definitely be going back to ACG for future work. read more

This is not one of the best...this is THE BEST shop in Southern California! I have taken multiple cars there and have NEVER been disappointed.

I was very cautious as to where I was going to have my E63 AMG customized. I'm a freak for perfection. I looked for the top facilities in San Diego, and these guys came up in the top 2. After meeting the principals of both as well as going to their shop, i chose ACG. These guys know what their doing and are fair and honest. They had Ferrari's Benz's and other exotic cars that they were working on. I feel really comfortable taking my E63 AMG here as you will taking your care here. Chris L. Cardiff read more

I had a great experience working with Sean at ACG. My 2009 GTR had a P0842 transmission error code, which is pretty rare and not a lot of people know what to do. ShepTrans rebuilt my transmission and Sean was able to work with Shep to diagnose the problem (faulty Sensor A), get it replaced and my car working again. I appreciate how Sean didn't take advantage of my situation of being relatively powerless make decisions about my car. I had to trust him 100% to make the right recommendations that were in my best interest. I feel like he did this and saved me a ton of time and money. I really appreciate the honesty and integrity Sean showed. He also had a few other recommendations for my car while it was down there, which ended up being things I had wanted, but didn't know who to ask or talk to about. Thank you Sean and ACG! read more
