Irregardless with the larger tires the pcm still thinks it is running stock tires. Thats the speed difference, not the rear end. You have 3.92's If at all costs next time you change the diff fluid, there should be a mark on the grommet, extending onto the pumpkin in white, Or the rvt red that dodge likes too use for a gasket.. If any of those clues are present, then the rear end hasn't been touched ,just my 2cts.
