Installed Tow program after installing lift with 35" tires. The shift pattern is much improved and seems to have more power than before. The calibration for the tire size is within 3mph at higher speeds and right on to about 50mph. No notice in mpg but when you lift a truck and put 35s on you cant expect any improvements. I would buy again just for the tow and mph adjustements. The only mod installed is a k&n air filter. Easy install great product for what I needed.
