Quality work from Matt and the team at DMS! I had my car in for a full motor refresh and rebuild with forged internals and necessary supporting changes to prepare for future boost plans. Matt was patient with me as I went back and forth on ideas but was sure to keep me going in the right direction. His experience and advice was critical to getting me ready for the next phase of my build. Would definitely recommend DMS as a top tier shop for your go fast needs!

Great Shop! Straight up guys and top notch work. True QUALITY

These guys have done 2 builds for me. One on my 16 Z06 and one on my wifes CTS-V. Both AWESOME jobs at a reasonable price. Their attention to detail and performance is unbeatable. Will be bringing them more projects in the future. Keep up the good work guys!

If you want more power these guys can give it to you

These guys are amazing and extremely talented at what they do, if you are looking for a top notch upgrade on your ride please go see the guys at DMS and prepare to be amazed.

First class fabrication, tuning and total performance.

Mathew Owen is very rude and unprofessional when handling business. We currently do business through my place of business but I wanted to start bringing some of my personal rides to him until recent incounter with him. I’m glad I didn’t make that mistake. Very unprofessional

Matt and the team really are the epitome of how a performance shop should operate. They take the time to connect with customer and make sure their concerns are addressed without any hesitation. Top notch customer service for your performance needs. Would most definitely recommend to anyone looking to build a solid and proven car. Thanks again guys!!!!

Got some parts for my lsa and have talked to Matt several times! Good guys and I appreciate there willingness to help!

I Ordered the DMS aux fuel filter kit for my V2. The steel braided hose they sent had a huge leak. Took it apart to find the inside was mangled. Had to go buy my own braided line. I was pretty upset at first but I understand mistakes happen. I was glad that Matt called me directly as soon as he heard about what happened and he apologized and worked with me to resolve the issue. He backed his word and made things right. Long tubes and id850’s next

This is my second project with these guys. Glad I came back for more.Very happy with the quality of work and customer service from DMS. Top-notch pros all the way through the projects. Thank you Matt.

Rad custom and specialty shop. Super clean. These guys take their time and do it the right way.

Forget about how great the car ran after they tuned it up. These guys are as cool as they come. Theyre true car guys and as smart as youll come across. AND the ZL1 ran like Usain Bolt when they were done with it.

Really great people and service. I drove 4 hours to get the best and you will want to as well

Josh answered the phone and was extremely helpful. They do not do motorcycles but he gave me the name and the number of a location right up the street that would help me. Most places saying no, sorry, get lost but these guys were excellent. I would suggest them all day long.

Very friendly and professional staff. They were super helpful when I needed to reschedule my appointment. Large and modern facility with everything from in-house hand made parts, to machines that can print out a custom set of wheels.

All of the people at DMS are extremely friendly, helpful, and patient. DMS isnt like most shops that try and just get you to spend unnecessary money, theyre extremely honest and will help you get the best bang for the buck. Matt is very helpful and answers emails fairly quickly. Before I brought my car to DMS I would be at various drag strips asking other GM owners where they took there cars, and I only asked the ones that were running pretty solid times and each guy said DMS. If you want your car done right take it to these people.

Best customer service youll ever come by. Love dealing with these guys.

Very helpful and knowledgeable in selecting the right part for my vehicle.

Matt and everyone at DM are super professional, laid back and they absolutely hands down know how to build and tune these cars right, the moment I walked in the door I knew I was in the right place, I have been referring ever since!

These are not tuners, but simple hacks and liars to boot. I took my ZR1 there on the recommendation of Calvo Motorsports. The car had been previously tuned by Lethal but was flashed at the dealer during a repair. Should have just taken it back to San Antonio. In short, when I picked up the car three days late, they could not produce an actual dyno sheet and made excuse after excuse even going so far as to tell me they were out of paper. But excited Matt told me the car made awesome Power which he said was 38 WHP less than it previously dynoed on the same style machine. Because the had no paper and could not locate the actual file, I left. Driving away the car died, puffed, and was detonating under acceleration. When I got home, I also found a scratch on the back bumper where they had closed a garage door on it, causing about 2k worth of damage. I emailed and called Matt, he said it could never be them, they would never do that... Whatever. I paid to get the car painted and took it to a reputable tuner in Houston. Their entire shop laughed when they learned Matt had uploaded a base tune that was publicly available on Corvette Forum. After another $1500 in tuning and verifying the engine was not damaged, I have my car back, at the previous WHP plus 2 after Lethal did it. Sure I can sue them, but they could never pay the bill; unless of course they steal it from another unsuspecting customer charging for a tune and uploading a forum file. Please, please, for the love of your car, dont take it there. Completely dishonest, and could not tune themselves out of a wet paper bag. If they happen to close their door on your car, they will deny it, refuse to look at security camera footage, and tell you they come from a long line of amazing tuners whatever the hell that means, and do noting to make the situation right. Run.

DMS did an outstanding job with my ZL1 Camaro! Awesome people to work with, Highly professional and the Expertise is second to none! Top notch quality and attention to detail! Highly recommended! Thank you!

Its all in the detail, and these guys know how to do it.

AN Fittings WOW!
