"I had put a 2.25 leveling kit with 3" blocks and 33"tires on my truck recently ..i bought this to compensate for power loss and mpg that i lost after installing. The programmer did excatly that. Since i only use 87 octane that's what i.had it programmed to. At 65mph i am getting 20.5 mpg and the truck seems more peppy. So important very pleased with the hypertech programmer." —James S from Rosharon, TX bought a Hypertech Max Energy Programmer for a 2010 GMC Sierra, 1500, 5.3L V8.
"the windshield mount is junk. I could not get it to stick even if I made it wet. They should come up with something better." —Daryl W from Bismarck, ND bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2010 GMC Sierra.
"This makes a slight difference in driving on the 87 tune. Haven't entered the 91 tune yet, but so far, the shift points are very slightly changed and makes a fair amount of difference in the truck. I wish there was a 93 octane tune!!!" —Kenneth H from Arab, AL bought a Superchips Flashpaq Tuner for a 2010 GMC Sierra, 1500, 5.3L V8.
