2004 gmc yukon xl denali 2500

Reviewed By shane f (Altoona, PA) Reviewed for a 2004 GMC Yukon XL —5/30/2015 5:13 AM

This programmer functioned as intended. It boosted horsepower about 10% which raised my average mpg by 21%. Three extra mpg may not seem like much, but when you're averaging 14 it really helps overall.

Range AFM Disable

Reviewed By Mark Z (MOUNTAIN TOP, PA) Reviewed for a 2015 GMC Yukon XL —3/17/2015 8:39 AM

Installed on new 2015 yukon xl. Takes a second to plug it in, and after 3weeks my mpg is the same it was without the disable. The truck doesn't have the low rumble in 4 cylinder or the bump when it would change from 4 to 8. So if my mileage is the same it's kind of a no-brainer. Only wonder about dealer picking up on it. I'll give it 4 star for now 5 star when there is no long term issues.
