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.

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.

Bully Dog Triple Dog GT Tuner (49-State Legal) Reviews

Buy it.

Reviewed By Michael P (Chehalis, WA) Reviewed for a 2006 GMC Sierra —9/23/2016 6:58 AM

After a month of solid research i decided to go with Bully Dog. Very easy install, excellent graphics, produces the best information from your vehicle. The Tow tune turned my sluggish truck into a sports car like feel to the drivetrain, great shifting, and perfect use of the 5.3 power band. If you have the chevy trucks made between 2000 and 2007 (classic) you should have this tuner.
