Speedometer calibration
2002 F-150 supercrew. Originally bought from dealer (new) with 33" & 4" lift. I added 3" body lift and 37" tires. At this point I had the dealer readjust speedo and they corrected as best they could, it was like 10mp off on the slow side. I added a supercharger and changed the gears to 4.88 and my speedo was off by like 30mph on the high side. Went back to the dealer, (they did the best they could?) and now my speedo is off 6 or 7 mph on the high side. The dealer says they cannot adjust any further. How do I correct.

How you doin'?
Welcome ! Ford mechanics know next to nothing about aftermarket modifications. Aftermarket chip tuners do this modification in their sleep. Call these folks: www.troyerperformance.com

yep like max said time to get a custom tune they will be able to correct for the tires and gears and get some added performance, it will really help to because you are using forced induction now you will be able to pick up alot of ponies this way i recomend mike troyer and the super chips 9100 custom tuner mike is a suporting vendor on this site and he knows his stuff, good luck

Thanx for the info you guys. I called Mike at Troyer Performence and I'm waiting for him to get back to me.
For right now I'm only really interested in the speedo calibration so I may go with the JET part.
My ProCharger states that it is a complete unit and if there is a chip that it needs to be removed and the computer returned to stock so that I can run full timeing. Always interested in more ponies though so I'll wait to see what Mike says.
I was also thinking of using a chip for the tranny pressures but I'm leaning more and more to the Factory Tech valve body.
