Do you have latest update on your sled one of the earlier updates had the Speedo calibrated wrong has to go to dealer to get this done.

This, or they put the wrong update in (3 different speedo calibrations for the 3 different driver sizes)

Update is vin specific so if it’s stock the speedo should be right with latest flash. So pull your chaincase cover off and ensure all the magnets are in rubber plug in end of driveshaft and that the polarity is flipped every other one.
