hmm... or if you have a low pressure area with no immediate plans to fix it, take your intake air from there? It could "detune" the engine the faster you go and allow larger throttle openings at lower speeds than normal and "maybe" reduced crankcase pressure.

Anyone know the effect of ambient pressure on a typical bsfc map?

The "oval" doesn't happen to move right with lower pressures by any chance?
