Since this was posted it bothered me. I asked my tuner about it as we were tuning a 97. We looked at it and the 97 Had just as much end user tuning as mine did. He told me that all OBD2 Fords have that with the Xcal2. On the Diesels we cant change the speedometer because it is run through the ABS but on the gas trucks we can...
