Today I went to RamCharger's and bought a HyperTech Power Programmer for my truck for $349.00. There are three different settings that you can program it... 56 hp w/ 94 ft-lbs torque, 77 hp w/ 130 ft-lbs torque, or 96 hp w/ 163 ft-lbs torque.It took all of a few minutes to program and the results are amazing.
One of the options is to adjust for different tire sizes, which corrects the speedometer if you have larger tires and also changes the shift points for the Allison Transmission. If I ever need to take the truck in for service I can re-program to the factory settings.
