Superchips Cortex Programmer Reviews


Woke up my 2013 Sierra

Reviewed By Timothy O (DAYTON, TX) Reviewed for a 2013 GMC Sierra —3/12/2016 4:39 AM

Have a 2013 Sierra crew cab 4x4, it ran good but with the Superchips programmer it now runs great! When I step on it the truck almost jumps. Maybe a slight boost in MPG. Highly recommend if you're looking for a performance boost.

I installed the easy tune on the F250, and took it out for a test drive and I can feel the difference in performance and also helped with the gas mileage.
