Hi all! Possibly a dumb question regarding changing revs per mile to adjust tire size using the old DRB3 on an ‘01 2500 4X4 Ram 5.9 Cummins.
Why am I having so much trouble with this programming? Every time I change the number in the abs module the speedo goes out of whack the opposite direction and by a huge amount. Any ideas? Thanks in advance!
