    Any 6.0 from a GEN 4 truck. So like a LY6 or L96 I believe. Either of those should be found in the heavy duty 2500/3500 trucks or vans.

    Those would be plug and play expect for the VVT as your 2008...

    With stock computers like these the main thing to know if that once a few basic things are set, they are to never be touched again unless the parts are changed or the fuel used in changed.

    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.

    Are you doing the change to the MAF and VE separate?

    Like putting it into speed density only with the MAF failed and putting into MAF only for MAF tuning?

    Is your fuel pressure staying solid...

    Smooth the table after each change. Using both the functions within the editor and doing it by hand. Get rid of the spike in the middle and smooth the rest out.

    Those aren't that large but you could have done the normal scaling for injectors over 63.5lb/hr. That being double the stoich, half the IFR and half the IVT terms.

    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.

    Some power enrichment and maybe a few torque mngt settings will make it less lazy feeling.

    Tuning the transmission will help too, you can make it shift a tad quicker and firmer without hurting it.
