TruXP Xtune Performance Tuner Reviews

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.

2008 Yukon

Reviewed By neal l (Lebanon, KY) Reviewed for a 2008 GMC Yukon —8/4/2015 1:14 PM

The Range AFM does just what it says. Keeps the vehicle in V8 mode. Gas mileage has improved some. Oil consumption has stopped. This vehicle used about 2 quarts in 2000 miles and after the installation of the AFM oil consumption is zero.

Jet Performance Module Reviews

Increased performance and mileage

Reviewed By Randal M (Templeton, CA) Reviewed for a 2005 GMC Yukon —4/2/2008 6:22 AM

I recently purchased a module for my 2005 GMC Yukon with the 5.3 liter Vortex engine and noticed changes immediately. The key I found was also adding a new intake like AFE or K&N to allow greater airflow as well as a new exhaust from the CAT back. In combination I am recieving an additional 4-5 milies per gallon increase. I'm not kidding about this and can prove my findings. Please note that it's really important to modify ones the driving habits, like not giving too much gas when excellerating. Overall, the module was well worth the investment and I hope that others will follow the same path. Enjoy!
