Shooting into the dark and just about hitting a bull's eye. How's that for lucky?

Very little on all accounts of SOI and ICP. PW can be whatever you want once you get above a certain ICP since you don't really care about economy once you get above 2000 PSI or so.

I would increase SOI a degree or two at the most below 1600 or 1800 RPM and at low fuel rates. ICP can ramp up a little more aggressively but again, you're trying to go for economy.

All in all it boils down to your right foot. THAT'S it.
