Yes you can program the TPMS PSI threshold or the dealer could do it for you if they wanted to. You need a VXDiag VCX Nano as a pass-through device so your laptop software can communicate with the car. You then use Tech2Win (2013 and older) or GDS2 (2014 and newer) software to program the front/rear pressures. You have to enter it as KPA instead of PSI. The software asks you what is the door placard so you would enter the KPA equivalent of what you want to run. Federal regulations require the low tire warning to come on when the pressure is 75% of what the vehicle is programmed for (which is the door placard if not changed).
