Bout this for my 2015 SS Camaro l99 and it makes big difference when you have a cai and catback exhaust!! Feels like I gained close to 40 hp to the rear wheels and the throttle response is impressive and quick !!! Good job hypertech !! ????????

Worked as advertised. My calculations say my tires are 34". With truck weight they measure about 33.5. That is the number I used and it put GPS spot on. Truck seems to be shifting back into 4 cal mode more regularly now helping to boast mpg. Worth the investment.
