2008 Hummer H2

Reviewed By Allan S (VICTORIA, TX) Reviewed for a 2008 Hummer H2 —2/12/2011 4:56 PM

I was averaging 12.1 mpg without any mods. After installing the superchips MPG quick download I could not believe I was actually getting 14.2 mpg with a best of 15.4 mpg . This is amazing since none of the three H2 Hummers I have owned ever got close to this with any other mods I have ever done. Sad thing is as soon as I installed a Volant cold air intake I actually lost all my mpg gain. I think I will throw away the Volant and go back to stock air intake.

Performed as promised

Installation wasnt as easy as stated, had to trim my "factory off road cover". But once that was done, this unit woke up my 6.0 LQ4. Had it for a while now, only bumped mpg by 1 gallon,,,, but worth it! Especially when I show other H2 drivers my readings!
