I'm pretty sure that changing the gearing in the pumpkin doesn't require recalibration...

You may be correct if Ford now measures speed directly off wheels, like by using the ABS sensors or something similar. On older models they took speed off transmission shaft that measured driveshaft speed. In those cases changing the rear gear ratio required speedometer recalibration.
