Awesome

Reviewed By Tyler G (Chapman, KS) Reviewed for a 2002 GMC Sierra —3/11/2011 10:51 AM

Changed gears and tires and the speedometer was off but the hyperpac put it right back on the money. Didn't notice anything with the added power. But love the gauges an awesome add on to the truck.

i would have thought that you could adjust between performance , towing ect. without redoing the whole set up. other than that i am completely satisfied.
