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.
