If it's your own tune not a"purchased" tune post it and some logs and I'm sure people with help.

What OS?

8594 OS. It doesn't seem to matter what I change, desired rail pressure in the tune WILL NOT match the desired rail pressure on the scan tool if it is different value than the tune came from the factory with. I can load a tune with every rail pressure table set to 180MPA across the board, and fire the truck up check it with the scan tool and it's still 30MPA desired. Same goes for WOT, 180MPA is MAX. I've checked over every parameter/limiter and it just cannot be raised.

I have the same problem with my 08 LMM. It is the 8594 OS as well.
