Did not adjust as many items as I thought it might. Easy to install. Just wish it did more for my truck.

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.

Worked perfectly to re-calibrate for larger tires as well as disable the TMPS for airing down the tires. Really like the colored screen versus the DIP switches I have had to use in the past with the competitor's calibration tool.
