Hypertech Max Energy Programmer for 2008 H3 Hummer 3.7L

Reviewed By Shawn J (CLOVIS, CA) Reviewed for a 2008 Hummer H3 —8/13/2014 11:57 PM

I wanted something that I could program myself instead of sending of my PMC to someone eles to program. I was able to change my tire size to compensate for the 33in tire I installed, also was able to change my shift point and shift firmness as well. It also came with two performance setting, an 87 and a 91 octane. I used the 87 octane in my 3.7 liter and I got a boost in performance and mileage as well. Which made me very happy.

Not bad. But not great by any stretch. It did correct my speedometer for my 35' tires. Small gain in mid range horsepower but theres a trade off because to really notice I have to mash the pedal in which case I lose a lot of mpg's. I get it, that, that is supposed to happen anyway but it seems much more significant to me now. Anyhow, its an OK product but I know now I probably should have went with something more high end. -2009 Hummer H3T Alpha 5.3L V8
