I get the part about "boost compensated fueling" in the AEMS (looks like a terrific system, btw), but I suppose what I mean't to ask was the reverse. IOW, does the AEMS also have "fuel compensated boost?" Will it decrease boost if and when the injectors max out and the AFR's go up?

Tim Bailey always told me to not run my highest sea-level boost map when I'm running at home (4K+ elevation) - he had me build a boost map that runs 2 lbs less boost for use at altitude. This was with an AVCR ECBS and EWG. I'd always thought the issue was the altitude induced change in PR which causes the turbo output to heat up. Am I mistaken?
