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.

Great tuner after a few tweaks...

Reviewed By Ryan J (FESTUS, MO) Reviewed for a 2006 Jeep Wrangler —1/17/2018 2:54 PM

Received tuner and purchase experience was wonderful. Initial installation for software was fine, however installing it in my jeep lj was not easy, at all. Had to call, customer service ans reinstall it again with an additional upgrade. All in all it seems to work fine and my jeep sounds quieter after the superchip.

Healeybrothers Review

Reviewed By Richard F (GOSHEN, NY) Reviewed for a 2013 Chevy Silverado —1/17/2018 1:25 PM

I work for Healeybrothers in the Hudson Valley. NY. I get to talk with many of the top mechanics in the shop. Since Chevy went to Active Fuel Management in there engines they use a considerable amount of oil when switching from 4cyl to 8cyl. There is no fix for this problem. I purchased the DiabloSport in Tunei3 to disable the AFM in my 5.3 engine. Very easy to use and I did the economy tune also removed the restricted top speed limit. Main reason no more oil consumption. Very simple setup
