I can say I am a happy customer of Mr C. He squeezed me in for a custom dyno tune 3 weeks ago and him and his crew worked non stop from 9:30AM until we left his shop at 7:45PM that night. His wife was calling him to eat and his 2phones he carries never stopped ringing. He ran from his machine shop to mill intakes back to the dyno room. He tunned 800+ HP out of a fully rigged blown 502. His shop is full of motors and boats from all over the country. Tyler I told you word of mouth advertising is priceless and it shows. You work your butt off and people respect what you do.
