Is there anyone in the Houston area who has a Superchips Tirepaq or some other programmer that can reprogram my speedo to be correct for my new 315/70/17s? Id buy you dinner for it.

You sure it isn't VIN locked? All programmers are, so they won't be adjust the speed-o.

You'll prolly have to buy a "tirepaq" fo yourself...

for the 04.5's, the dealer can recalibrate the speedo by using "revs per mile"....

nah...from what I have heard, that is only a limitation with the 06 and newer third gens. Pre-06 trucks should still have the revs per mile option in the starscan tool.

I have heard it was on the 06+ trucks that can only be calibrated up to a 33" tire as well.
