New user here with LOTS of questions....but I'll start with this one! I have an 04 F-350 6.0 and recently started using Forscan and cannot figure out how to adjust the tire size for my truck for proper speedometer and mpg calculations since, I went up from the stock 265/75's to my current 315/75's! Any help would be greatly appreciated! Thanks in advance!!!

On the 7.3 and 6.0 trucks, the speedometer & VSS signal is generated by the ABS module, so it is the ABS that needs to be reprogrammed. I don't have the Extended FORScan license yet, so I don't know if it can program the ABS module.
