Hypertech Calibrator keeps it all legal
Purchased this after having my son's truck lifted with 35" tires. We wanted to capture his desire to have the look of a big truck while still maintaining the correct speedometer readings and transmission shift points. The system does require you to use a Windows based PC to update the unit to the most recent software package (it is not Mac compatible), but other than that it is very straight forward to use. Hook it to the OBD port, input your tire size and allow it to update your ECM, that's it.
