Hypertech Max Energy Programmer Reviews


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.

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.

Superchips Flashpaq F5 Tuner Reviews


Superchips tuner

Reviewed By Danny G (farmington, IL) Reviewed for a 2013 GMC Sierra —3/22/2017 3:31 PM

This is my second superchips tuner I have purchased, one for a 2009 Sierra and this one for my 2013 Sierra. Combine this tuner with a good cat back exhaust and cold air intake setup and you can tune your truck to run the way you want. Very happy with the ease of use when connected and making changes. No going to the dealer when installing larger tires to get the speedometer reset.
