C7 ZR1 2019

The final edition for the C7 platform gave us the ZR1, an incredible platform that has amazing potential for more power and some seriously impressive track times. Unlike others we purchased a development car to validate our packages, and process on this platform. As tuning these is unlike any of the other C7 models before it. If you are not careful in both the execution install, and tuning you will be left with either a sub par running car. Or a blown up engine on your hands. You can feel confident knowing we have done the grunt work in determining what works and what doesn’t and ultimately allowing us to provide you with a very proven package that you can enjoy for a very long time.
