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.

Hypertech Speedometer Calibrator Reviews


Does as Advertised

Reviewed By Chad M (Midlothian, TX) Reviewed for a 2015 Ford F-150 —8/15/2015 8:16 AM

It calibrated my speedometer since I put larger tires on. It takes trial and error. Just because you put 35" tires on doesn't mean you just set this to 35". You have to test it. I have 34" tires. Had to set this thing to 32.5" for the speedo to be accurate. Unfortunately, this is my only option at this time since the tuners are unable to calibrate the 2015 F-150 at this time. Dealership wanted the same price as this calibrator for a one time change. Good product.
