you will need a speedo re- callibrater or a power programmer with a recallibration option.
No way around it unless you just wanna have someone "pace" you at a steady speed. Then, at least you'll know how far it's off. That gets old fast--always doin math in yer head.

If your speedo is computer controlled then any mechanic with a "GOOD" scanner should be able to recalibrate it.

Superlift also makes an inline calibrator specifically for trucks & suvs with larger tires. I think they call it truspeed and it is supposed to be very user friendly.
