The Perfect Tool

Reviewed By Jim W (SAINT CHARLES, MO) Reviewed for a 2014 Chevy Silverado —10/11/2016 8:12 AM

Absolutely amazing investment. I couldn't ask for more. This thing can change just about everything in the vehicle, and has the ability to be custom tuned. Couldn't ask for more. I will be getting a custom tune from Lew soon, highly recommended product!
