This weekend I added the XRT PRO after doing a CAT/DPF delete. Only running the mild tune (+60hp). Everything is working great except for one thing, the speedometer is reading 6mph high @ 60mph.
The manual shows a selection for tire size calibration, but when I check the tuner this selection is not available.
What am I doing wrong? Is there a problem with the tuner software build?
Thanks!
