has anyone reprogrammed their speedo using either the ford WDS or IDS. today i was playing around and my axle ratio is 63.10 i believe with teh stock gear ratio of 3.27. i think with 373s it came to be 71.xxx. but anyways i can figure out a way to do it that way but if i reprogrammed for a bigger tire size, like a 29inch would that get in the ballpark? ill buy a predator or sct soon enough ut just for now i dont want my odometer going nutzo on me. if anyone has done this lemme know. my mind is getting boggled
