After the EcoHubs and the original 3.90 gears are installed. when I take it to caterpillar service to have them reprogram the eco speedometer doe anyone know the ratio? I think it was a ratio that was needed, its been 6 or 7 years ago that I had them change it for the 3.07 gears. Or is that something I can program myself using the software I got from Superman? Also why is the overspeed on the CTIS recommended to delete it?
