Easy to install. Noticed increased power right away. Acceleration and shift points are great. Haven't switched program to tow mode yet.

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.
