Speedometer Calibration

Is there a way to calibrate the the speedometer myself..?? I have a 99 f250 7.3 PSD. I heard somewhere one can calibrate the speedometer through the on board computer.. Or have I been misinformed??
A tutorial posted somewhere or a link would be helpful

Thanks

You can take it to your dealer, buy a chip/programmer, or buy a truspeed unit.

Did you check the tech articles, I found the instructions on how to do it yourself around here awhile back.

I know you can recalibrate the speedo on a pre-99, but the Superduties don't work the same way. I think you've got to take it to the dealer.

Speedometer Calibration

Hey Quad,

Got the reverse shackle kit put on last weekend, it does make a significant difference. Edlebrock didn't make a set of the IAS shocks that would work for the lift so I changed everything out to the Rancho 9000x's so well see if I can tweak the ride to what I want. The only thing I haven't tried know are the Bilsteins

Shoot me those instructions if you get a chance, I still need to calibrate mine.

Thanks
Brian
