I added larger tires to my 2016 Silverado. I wanted to be able to input proper tire size for the vehicle. This device made that easy. I was also able to turn off the afm, which is nice. Surprised at the amount of adjustments that are available for shift points. Something beyond my needs so I left it alone. Very pleased for the money spent.
