“I like Finish Line Performance because Dan educates you on the issues involved in tuning your vehicle. He does a thorough job as he's completing the dyno test at a safe pace.”Harvey W.
“Had a cam installed on my 2012 camaro by another shop and never really was satisfied with the tune. Took the car to finish line about a year ago and Dan said he thought he could make the car run much better. I decided to have them install a rear diff 3.70 gears and tune. Very glad I did. I am now a year in and couldn't be happier on how the car performs. Dan did a great job tuning and Tony was very responsive to all my questions. I will be going back..”Geno T.
