"Very professional and friendly service. Everything was done right the first time. Ryne and his team are top notch!"

-Wicked C5

"The first thing I noticed about CMS was their straight forward and honest approach to customer service. After my first discussion with Ryne, I immediately knew I found a performance shop that I could trust. Since then I've had two C6's tuned by Ryne and could not be happier with the results. He takes the time to street tune AND dyno tune each vehicle to find the perfect balance between max power and safe drivability."


"I went to CMS to have a Kenne Bell super charger installed on my '04 Z06. Mike did an excellent job with the install and Ryne's tune managed to get me over 500HP with 7psi boost and a conservative tune. I was impressed with the skill and customer service of CMS. I couldn't have been more pleased."
