Changing Tire While Building a Tune

[DieselDix]

Determine the % off your speedo is and either add or subtract that % from the 8000

Basically just change the pulses per mile?

[2007 5.9]

Yes change the VSS pulses for the % off your speedo is

Alright so I have tried changing the VSS pules for the percent the speedo is off and still no luck. Does the Smarty S06 require a "VIN License" to be able to help with this problem?

Not if you follow the steps that I outlined above.

Just to be on the safe side I would but not required.
