With having larger after market tires on the truck and checking my speed with my GPS, I was moving 4 MPH slower than my speedometer was reading. After a couple of programming attempts to dial in my tire size so my speedometer would match my GPS. I am very happy with the results. Now my truck runs a lot better, transmission shifts better, and PMG improved.
