Easy install and start up

Reviewed By Darrel H (PASO ROBLES, CA) Reviewed for a 1999 GMC Suburban —8/22/2014 5:45 AM

It was as advertised. Easy to hook up and so far works perfect. I was able to do a milage tune , then a performance tune and could feel the difference. Also cleared an engine code. Excellent piece of equipment.

Tuner works fine

Reviewed By Keith B (New Berlin, WI) Reviewed for a 2008 GMC Yukon —9/4/2015 5:07 PM

The tuner works fine on my 5.3L GMC, but I was unable to get the Software to work, even after contacting Edge the maker of this product. I really only wanted to be able to disable the Active Fuel Management, but this unit does so much more.
