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!!

Great Product

Reviewed By Eric S (Weston, WI) Reviewed for a 2004 Chevy Silverado —1/22/2014 10:49 AM

I purchased this unit to get better mileage and performance out of my truck. I have dual exhaust and a CAI for performance mods. Install took a bit longer than expected, due to finding the right fuse and wire routing. I have not ran on the premium yet, which requires premium fuel. Waiting until it warms up. I have noticed an increase in power when i have it on the tow tune. I am waiting until it warms up to really see any mileage increase. Overall, it is a great product.
