Superchips Cortex Programmer Reviews


Works very well in all modes

Reviewed By William J M (Moncks Corner, SC) Reviewed for a 2006 GMC Yukon XL —11/23/2009 6:07 AM

I like the box so far. I've run all modes at times and like the benefits of each application. I am going to most likely run 87 octane setting. Have a custom tire size entered. That was such a NICE feature. Have modded the shift pressures and points in a custom config. Overall, I am happy with the product. GLiDE

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.
