Questioning whether to buy it?

Reviewed By Cameron S (PENSACOLA, FL) Reviewed for a 2007 Hummer H3 —11/20/2012 5:55 PM

For GM trucks it's difficult to install due to the small space (30 min. install). After 2 days I noticed performance increase- smoother shifting at different rpm points, more horsepower. DON'T BUY THIS TO SAVE FUEL- it might save you 1 mpg if you're lucky and drive normal, but you'll be wanting to "test" it out so much you'll start loosing fuel mileage. I have this with a JET MAF sensor and a K&N cold air intake all recently installed- total extra mpg w/ everything 3mpg but a big notice in HP.
