Speed Calibration and Gryphon
Well I have been looking for a few threads both on here and on F150online.com for my tire size to lock in and have no luck. When I go to calibrate the gryphon to my tire size it will not hold it. I load previous settings and no luck it is stuck at 23XX and I need 2470 for my 35's. How to I make it lock and save in there? Thanks!
