Carbon packing issues are done by dirty combustion. Should not be problem the tune runs so clean any ways. EGT would slightly depend on how smooth you want to make it but it is timing and boost vs power that effect it the most. I think those can be tweaked to bring it back in spec pretty easily. Power loss should not be an issue at all because the ECM knows how to make proper power with it already. If anything then maybe it would be smoother more consistent power with less vibration and allow for even higher settings with less risk?. Seems reasonable.

Oil don't lie. Slightly lower efficiency in a tune made just for all high fuel mileage and not more power maybe someone would see slight difference but it still should not be going black again thou.

The one I drove, the the manifold temp was slight lower after test driving it than it was before the update. Hard to tell but was not different so much to notice. the truck had 575 hp in it and it was very smooth. had to watch speedo because it would get up to speed faster than expected.
