    What MAP are you using?

    Your map kpa on key on and when you shut it off is rather high at 105-106kpa. It should match where you live. Like 100kpa key on engine off would be at around sea level.

    If you use the LS6 injector, you must use LS6 injector data. The 5.3 truck injector data will be wrong. Once those settings are changed, you do not touch them again unless you change injectors....

    The gas to diesel difference I'm sure does make it different like you said. I've never worked on a diesel truck with the 6L80e before.

    Did you check fuel pressure with a manual gauge?

    The channel you are logging for fuel pressure never moves, perhaps that channel does not work as there is no real pressure sensor on this vehicle.

    Probably a bad MAP.

    Your key on engine off KPA readings are 229kpa, just sitting there. Should be right around 100kpa if you live at sea level.

    They are likely doing a write entire with a Flex Fuel file. So the OS doesn't matter really because you are going to start with a new tune. It can be costly with credits doing it this way.
