Its well known that diablos tire size programming can be a little squirrelly. Take a tape measure and measure the actual diameter of the tires with weight and squatted and use that in the diameter area. Or trial and error. Lower the diameter in increments until its dead on. My 37s are correct with the tuner programming my truck for 35.5.
