I was thinking the requirement for the higher values, was due to the fact that the ECM is calculating less PW because there is much less air density. Less air should need less fuel, so to make up for that in the calculation, I gotta swing these values way high to compensate.

Nevertheless, I have the tune working OK right now I think. So far the baro update deal seems to be solved. It's getting fun: she's loosing traction at about 50mph, with only 5psi haha.
