MTI Racing

"Had a corsa exhaust installed on my C8 it was great. Will and the guys at the shop do great work"

"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."

"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!"
