Pretty good tuner

Reviewed By Thomas J (JENKINS, KY) Reviewed for a 2013 GMC Sierra —7/18/2015 9:13 AM

Truck feels much better after turning AFM and torque management off. Took a few days to really notice. Installed the 93 "hot tune" as well. Don't expect smoking burnouts or a Camero killer but the truck does feel better to drive. I recommend it just for the fact that you can turn off the factory restrictions and AFM, but for straight up power gains I recommend a custom tune. That's my next route.

Everyone knows there is no replacement for displacement. V-8's are made to run on 4 cylinders. Shifts better, performs better, and no hesitation...Awesome product!

Great for larger tires for speedometer and extra power to turn them.
