smokindave So tonight after work I pick up my Renntec tuner.
Yup Im excited and hope to race a buddy in his supercharged Cadillac ctsv and kick his butt later tonight.

A famous person once said too much is never enough!lol

Mind you that quote came from Kieth Richards of the Rolling Stones!

12-13 s550 Renntech tune

Im just wondering if anyone has tried this Renntech tuner on their ride?
What would make my car more desirable to me is to be able to beat a friends 2018 Cadillac ctsv.
Just wanting to know how the drivetrain holds up with more torque and horsepower.
Thanks in advance.
