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.

Notable Performance

Reviewed By Kevin B (LAKE CITY, FL) Reviewed for a 2004 Dodge Ram —4/3/2015 7:53 AM

Had this for about a month in my 04 Ram 2500 5.7 and could tell immediately a little extra punch on the throttle. I think I like the modified shift points the most. However, running in 87 octane mode the whole time and lost about .5mpg - I was sort of expecting a little improvement here. It does seem to idle a little smoother too.
