Well im not sure what exactly discount tire set mine at but they did change them so my light wasn't going off at 60-65psi. That and i recall there being some sort of adjustment procedure in the manual.
I tried the one in the manual on p239 all 11 steps and I currently have it at 50psi with no light, but thats where I had it at the other day and then it come in again when lowered to 45psi
Dealer can do it. My friend who is a diesel tech at ford said that i. Can bring my truck in and he will adjust it down. Said he thinks 50 is lowest it will allow though. He said this is a new software that is only available for the 11+ trucks. Not the 08-10
