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.

Only up to 33", from what I hear.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.
