2010 GMC 4x4

Reviewed By Mike L (Tulsa, OK) Reviewed for a 2008 GMC C/K 1500 —4/28/2011 9:04 PM

I can not belive the improvment. It really woke up the truck. It makes the 6 speed trans shift at wide open throttle instead of a 4 sec delay. I lined it up aganst my wifes 2010 Avalanche and it pulled it by 4 cars by 85 MPH. A great product well worth the money.

Fantastic capability

Reviewed By Kenneth W (SAN ANTONIO, TX) Reviewed for a 2009 Ford F-250 —5/12/2015 6:09 AM

I've noticed an increase in mpg of about 2-3% in the Mileage XS Saver programming with my truck which translates to about 20 miles per tank more than the stock program. I will say that the 87 Octane program has noticeable changes over the stock program. My truck has the 5.4L with the 3.73 rear end. I am running a K&N cold-air intake with an Airaid PowerAid throttle body spacer. In the Performance program I have trouble keeping my foot out of the accelerator because of the increases!
