This is a great programmer to have, especially for wheel size changes.

I set the tuner for Towing, turned off the seatbelt chime and disabled the speed limiter. I am pleased with the much better throttle response and,after towing my travel trailer for a couple of hours, noticed better placed shifting while going up hills. Overall, I am happy with the tuner.
