New gears and speedometer.

guys im putting some 4.88 gears into my 2003 king ranch. i know i have to change the calibration on the speedometer, is the 03 changed with a programmer or with a new tiny gear in the side of the transmission case i believe. I am also going to be putting 35's on the truck as well. i know that hyperteck makes a programmer but only goes up to a 34" tire. would an edge programmer do it.? some of the other ford forums have lots of info but the answers are all from years back and some of the terms im not familiar with.i fix air conditioning not trucks! maybe the technology has changed.
any help is appreciated.

A programmer will recalibrate the speedo. You'd have to ask Edge or some other programmer company what tire they go up to. I've got an SCT xcal3 but not sure how big a tire it works for. 97-98s you need the actual speedo gear, thats what I had to do for mine when I swapped gears.

Whaddya mean I dont pay my bills?? Whydya think I'm broke!!
