01 MM EFI with PC III - high altitude adjustments

[a2wheeler]

I dialed in my PCIII near sea level using the butt-dyno. Now that I'm at 6000 ft, does the PCIII adjust the fuel and timing for altitude. My guess is that the fuel might get leaned out based on the barometer, but do I need to increase timing a bit across the board. It just seems to be a lot more sluggish than I would expect. And I understand that it will loose power at altitude no matter what.
