who has actually checked their speedo accuracy after PPE calibration?
The reason I ask is Ive updated the PPE STD programmer like 4 times, and no matter what tire size I plug in, it has absolutely no effect on the speedometer reading. I've checked it with gps, and no matter what its always 10% (the tire size difference). I am convinced that the calibration feature just plain does nothing. Has anyone else expereinced this?
