GTO power with Hypertech

Reviewed By Abram L (LA MADERA, NM) Reviewed for a 2004 Chevy Silverado —5/3/2017 7:15 PM

Made a believer out of me! Haven't had that kind of power since my 1967 ram air GTO. Happy with it. Plus drove to Mexico and drove 80 mph and got 19.3 mpg, "640 miles" can't beat that, wow!!
