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.

Only problem I had was installing the file on my computer. After that it was a breeze and yes the support team was helpful and polite. You get what you pay for so for me the price is rite. The touch screen could be a bit more responsive other than that, GREAT!!! programmer. My 2010 regular cab TRX4 4x4 with the 4.7 blows my buddy's 2015 Hemi out of the water after dual exhaust,intake,performance plugs,throttle body spacer. thumbs up for Diablo.
