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.

The ease of the installation is hard to believe. Then you start up your car , and away you go. The instant I took off in my hummer I had a huge smile on my face. I then took my daughter for a ride and watched her face as I gave my truck somme juice---and she said " dad what did you do to "Jake" [my trucks name} "? I told her about your programer, she said " AWESOME" !

Took a little to get going but works well.

I am overall very impressed with the tunes. It took me about a week working with support to get the tuner working on my truck. The support staff was great to work with. The tuner is showing some MPG gains and it let me correct my spedo. The tuner also seems to hve added a bit of low endo power which I like. I dont tow but I do have the truck lived 3" with 33's.
