"The hypertech max energy does everything I need it do. It reprogrammed my tire size and it makes a noticeable increase in mpg. however i cant help but feel just a little disappointed because it is not quite as customizable as I had my hopes for. But still a good product and I am satisfied with my purchase." —Nicholas S from Hurdle Mills, NC bought a Hypertech Max Energy Programmer for a 2011 Chevy Silverado.
