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.

best increase for performance for the $

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" !

Not what I was expecting

Reviewed By Daniel B (RIO RANCHO, NM) Reviewed for a 2013 Dodge Ram —6/21/2017 8:58 PM

I'll start by saying I was skeptical. First time using a tuner and I know it should help but never really thought it would be all that noticeable. I used the canned 87 octane tune as I use my vehicle for commute by it really did make a noticeable difference. Much more response with better economy, it's a double win for me. Can't imagine what a 93 custom tune would do for it! If your a first time buyer I would definitely recommend you try it out, you won't be sorry.
