Who Has The Tpms Pressure Maximums Raised On Their 08s

[Lincoln30]

My truck is at the dealer and they can't figure out how to raise the max pressure warning from 45psi to something higher (like 50). They know they have done this before on some 07s but can't figure it out on the 08.

 

Has anyone had this done on an 08???

You might want to find another dealer - it seems to be pretty straight forward - at least my dealer said so. 2008 Avalanche - changed to LT tires and dealer raised pressure limit to accomodate load range E
