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.

Great Product!

Reviewed By Luke S (Wayland, MI) Reviewed for a 2002 GMC Sierra —4/19/2010 8:08 PM

I love the tuner, I'm very glad I got it. The only thing I don't like is how it's over $300 for just a one time use part.. I guess that's just life though. Would definitely recommend to anybody who's looking to get some extra horsepower without tearing apart your motor
