I've been waiting and communicating with Superchips since Nov '13 over the TPMS that won't accept an input under 29 psi. I have 34.5 tires and 4.56 gears. Had to trick the unit by using a bogus tire size of 33-something to get correct MPH. They work for some, while others never seem to overcome issues. I would not re-buy.
