411 P01 PCM running 3 Bar OLSD OS: 1263016.
Procharged LS6, large cam, low vac at idle (72 Kpa at 100kpa baro).
Tuned VE to under 3% error at 700'. Runs excellent all around at that altitude.
Problem this weekend: Drove from 700' to 6000'. With the altitude change, Fuel was showing 15-25% lean part throtttle/out of boost. I'm seeing Kpa levels at altitude with some throttle that I'd only ever see at no throttle decel at sea level.
Is there a way to add correction for barometric changes? Any strategy to pull baro from the map sensor would just max out to 105kpa whenever I get into boost.
