ADM Performance

I've been dealing with Andy for over seven years, and it's been the most pleasant experience. He's a straight shooter and does fantastic work. If you have a GM product, take it to him. He's building a motor for me right now, and I can't wait to get my hands on it.. Great guy and great service!!!!!

I have a 2011 Convertible Camaro that had the stock L99. Andy at ADM Performance, did a LS3 conversion, installed headers, new air box, new exhaust and changed the rear end differential gears. My car is turning 440 rwhp and still gets 21 mpg at 75 mph. My car sounds great, runs great and is very reliable. Thank you for giving me a true America made sports car. I am very, very impressed.

If you have a 6gen Camaro and want more power Andy at ADM is the man you need to talk to. He stayed under my budget and still got the power levels I wanted, the car is running better than stock and sounds amazing. I would send family members to Andy he is very trustworthy and upfront about what's possible with your budget.

Andy and his guys are fantastic. Just got the LT4 Supercharger in my 2016 Escalade and the best upgrade I could have done with DFW’s best LS shop!

Took a 2014 Vette to ADM for a performance upgrade, added a Z06 supercharger to the car. Talked to Andy a few times and could tell he really knows his stuff. He is a big Camaro guy but the motors are really the same. I have to tell you he did what he promised and then some. Got the Z06 supercharger installed plus headers, x-pipe, & high flow cats.
Andy also does his own tunes on the Dyno. Top notch on all work and a lot less than any other shop in Texas quoted. I checked with all the "well known" shops.
Just another note: I took the car into Chevy Dealer for recall work and the Service guys and shop tech's were really impressed with the work Andy did. They couldn't believe a speed shop did a Z06 supercharger and put everything on the car just like it came from the factory.
Quote: " Everything is bolted, secured, and in it's place as well as a factory build Z06". I personally think that speaks volumes about the quality of ADM's work and their shop.
