    What parts of the tune are you having issues with? What have you looked at and done already? Can you include the particulars about the engine? Is it stock besides the BTR Stg3 cam? If not, what's there?

    A big thing which is jumping out at me is your ECT is pegged at 199F ... It doesn't move at all throughout the entire log. Have you checked your wiring to it? Once you get this figure out, then see how it runs.

    What size is the engine? In the tune it still shows it to be a 4.8L ... A BTR Stage 3 cam and 8.1L injectors would be huge overkill for this, so I'm assuming it must be bigger? If it is bigger, these need to be adjusted in the tune.

    I'm sure I've just scratched the surface here. Someone with a lot more tuning knowledge could probably help more.
