Absolutely criminal business. I agreed to spend $1,000 for a tune, MTI talked me into $5,000+ repairs that the car "needed" for the tune. Got the car back and the tune was not even done correctly. Tried for months to get them to make it right or give me my money back, and they kept ignoring me, now I'm getting a lawyer involved.
*Edit. I’d never once mentioned that the car was damaged in anyway. Yes, I said the car was modified by the previous owner and provided you with all the information that I had along with pictures. I kept reaching out and either didn’t get a response or was told it would be weeks or months before you could get me back in there. So basically after you got your money, you had zero intentions on making it right. And that is when I decided to get a lawyer involved, all you had to do was the right thing. And I have the entire conversation history to prove it. The least you could do is give me back the $1,000 for a tune that your techs were unable to do. That’s beyond responsible for the way I was treated.

They perform a number of work on my 1999 Corvette now I went from the slowest thing on the track to even give them hell cats some hell…… I do not let any other company do any work with Michael that they always keep it covered up when they have it they treat the paint job like it’s brand new and give me the most respect when I show up to drop my car off. The employee wheel is the only one that I talk to you when I go there no me and my car will and I wouldn’t take any other place.

This is an adjustment to my initial review. The number I was calling was not the correct number on the website. They called after seeing my review and were very apolgetic. I am now scheduling work on my new C8 Corvette.
Thanks Greg

Outstanding work on my Dodge Charger R/T!! Been coming to this shop for years and I am highly pleased with the quality of work and performance improvements done to my Charger. The car runs incredibly smooth especially at over 100 MPH and with the X-Pipe and the other mods my R/T screams. Safe to say my money has been well spent and Mr. Reese, Will and the rest of the MTI crew have done an incredible job and provided the best customer service. I really appreciate the insight and knowledge the shop has given me over the course of my build and throughout the stages I have gone through so I really appreciate them putting me in the right direction. All I can say is dont sleep on MTI they really are an engineering powerhouse. Can’t wait to come back for the Whipple Supercharger 🙌

Stay clear of this shop. The business practices are shiesty, the work isn't quality, they don't take ownership of their mistakes, they overcharge, they change the price once the vehicle is completed. Will the so called GM is very unprofessional. Everyone please stay away.

Fantastic service, professionalism, and completely customer focused. I used one LS Tuner in the area and they were a flop. I spent just over $18,000 in last 4 years with them. I could not get any problem solutions from them because "they" could not duplicate the problems. MTI, "Will", just asked for the problems. MTI identified the root causes and solved the problems; no duplication actions on my part required. MTI solves the problems. I had them re-tune my very, rare 2009 Pontiac G8 GXP; it is faster, perfectly reliable, screams at 620 hp and no problems!!!!!!

Will and the MTI "gang" will positively improve your car's performance with superb mechanical knowledge and professionalism. Another "tuner" in Woodstock, Georgia originally put a Magnuson supercharger on my Pontiac G8 GXP. Their follow ups on my problems with the "tune" and performance of the vehicle were less than satisfactory. MTI Racing completely turned those problems into great solutions. Try out MTI Racing before you decide on another "tuner". You won't be disappointed.

Was dealing with an exhaust issue that was throwing a check engine light. Went to the dealership who not only misdiagnosed the issue, but also wanted 3x for their "fix" compared to what the crew at MTI did it for. Extremely knowledgeable and friendly crew, would recommend and will be back for future services.Service: Exhaust

Amazing customer service, work and people! I have been to a few other well known shops in the area and always left those shops disappointed in the service. At MTI, I received multiple updates on my vehicle each week while it was there without asking for it. Always very honest and transparent with what is happening to the car. You can tell MTI works to form a lasting relationship and not try and over sell you to make a few extra dollars. Highly recommended!

Great service and people! They ported my ls1 throttle body, and did a stellar job. Extremely fast turn around. Will definitely use them again.

Stay clear from this shop. The quoted me a 2 week turnaround then had my car for a month and a half. My car has been sitting for a month just waiting to be tuned. The constantly say they will call to give updates but never do. When you email, call or text them on instagram for updates either they dont respond or respond with an attitude. Continue to make excuses on why your car isn’t ready. First it was Reese (the owner/tuner) car kids got in a wreck (don’t get me wrong family comes first) but he took the whole week off. The following week he magically gets sick and takes the whole week off. Its just excuse after excuse on why the work isn’t getting done. Went up to the shop multiple times to figure out what’s going on and the car was sitting in the same spot every time untouched.Came to pick up my car and they expect you to pay for work that they didnt complete. Didn’t want to give me the specs to the cam that I PAID FOR. Put my car at a different shop they fixed what MTI messed up and tuned the car. Had the car back to me within 2 days.
