GMC '02 2500HD

Reviewed By Bob J (Springville, UT) Reviewed for a 2002 GMC Sierra —5/17/2013 6:10 AM

I've long been skeptical of the tunes you might get from the simple programmers but relented to try it out on my GMC 6.0 gas it worked flawlessly, easy to use, simple and straight forward. I had the info in and its never run as smooth and started as fast, a 1 second crank and its running no hesitation, most of all the tires now match the speedo. I'm a believer. Bob J.

The Way TO GO

Reviewed By Richard C (Temple, TX) Reviewed for a 2002 GMC Sierra —3/16/2013 7:35 PM

This programmer really "wakes" my Duramax up! The Extreme setting gives you the performance. Tow mode allowed me to pull my 35' 5th wheel TT at 75 - 80 with out a strain, getting 10+ per gallon. Enconomy mode boosts mileage an easy 5 to the gallon, if you can keep from playing with the wanna bees, cause even the economy mode wakes the engine up! Making this purchase was one of the best automotive moves I've made since I bought the truck in '02.

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.
