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

Even Works With EFI Live

Reviewed By andrew s (St George, UT) Reviewed for a 2008 Dodge Ram —11/16/2015 10:25 PM

I bought this to fix my speedometer on my 2008 Dodge Ram 2500 Diesel. I was running 37" tires and went to 35" tires to fit a spare under the truck. I couldnt adjust my speedometer with EFI Live that I already had, so i bought this. It worked perfectly without having to reset the truck to stock. It took me a while to get the truck perfectly calibrated but now its dead on with my GPS.
