It does everything you need it to do plus more. A must have for today's vehicles.

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.
