Calibration in the tune. There is a gear/tire size table that calibrates the speedo.

Don is correct, the calibration is in 100% control of the speedometer output going to your dash. If it is incorrect, then the tuner just needs to make a tweak to the speedo segment in the tune.
H0101 and h0104 are the table names in EFIlive software that need modified.
