Perfect in every way. Very nice and educated. Honest person and honest work. Finding that in a mechanic shop is hard. Will always go here for any mods. Andy is the best!

Excellent place to shop for aftermarket performance products for vehicles

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 whats 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!

TOP NOTCHGoing to start with that I live in Wisconsin and my experience with this company has been awesome. I have been communicating with I believe to the owner over the phone on what I thought was a difficult and unique build but the guy has all the answers and definitely making the process easier. I am using a local company to install and tune/dyno and wish I could just ship my car to him to complete. I am ordering everything from him direct and wouldnt recommend anyone else.

Ive had ADM work on several of my cars and the quality of work definitely meets my expectations....and Im very particular. I would recommend this shop to anyone that wants performance work that comes with great workmanship.

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.

I got a dyno tune on my camaro and i gotta say I love the work he did on it. The staff seems very knowledge and they know what theyre doing. Would recommend to anybody looking for anything performance wise and specially if its Chevy related.

I bought the lt4 kit for my 15 5.3 Silverado and I have been seriously impressed from the first day I called. Andy was super knowledgable, he was able to answer every single question I had and point me in the right direction. The kit was extremely well put together and super clean. Everything need to plug, dyno, and play. Would reccomend to anyone.

I really dont like the name of this company. I hear it, and I want to immediately throw my guts up. Who is ADM???? Did they misspell Adam ? Every morning, I think of 10 things I am grateful for, and usually all 10 are the fact that I never have to visit this place again. The only reason I gave them 1 star, was because I couldnt give them half of a star. They wouldnt work on my Delorian, only because I wasnt dressed as Marty Mcfly. Complete B.S.

I called ADM asking for a quote to install a lsa supercharger on a 2005 vehicle. I was told they do not work on any vehicles older than 2010 and they lacked the proper software. Makes me wonder how they were able to complete any of the builds posted on their facebook page that were pre 2000.

Andy is the real deal. He is well known on the Camaro and Corvette forums for his tunes and LSA upgrades. He maximized my potential on my ZL1 and I was the most pleased. Very approachable and knowledgeable about GM products.Give him a call, you wont be disappointed

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 techs were really impressed with the work Andy did. They couldnt 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 its place as well as a factory build Z06. I personally think that speaks volumes about the quality of ADMs work and their shop.

Super service ..
