Thanks for bringing this up again, I just got my F250 and have the 5star sct from my F150 and plan to tune this once I get some miles on it, maybee by the end of the year, if I can wait that long. My tpms trips on at 55 psi so I set my tires at 60 and when the night temps drop it goes off and you have to take them to 75 psi to reset so I now keep them at 65 psi which is to much unloaded. Door sticker says 75 front and 80 back, I actually dropped each tire one by one and tested to see where it trips and resets to see if there is different front and rear setpoint which they all tripped and reset the same. Hopefully they will figure it out soon.
