[QUOTE="Anybodyhome, post: 440828, member: 19161"] So, how was the calibration done? If you simply entered a 33" tire diameter into JScan or a ProCal, it's not accurate. You should really measure the height of each wheel/tire from the ground to the top of the tire, figure the average and use that. Just plugging in 33, when it's really closer to 32 is going to throw it off. Do you know if the JKU was re-geared at any time? When you get to cruising speed on the highway are you easily running in 6th gear or are you having to downshift at the slightest incline? [/QUOTE]
