your wastegate is maxing out too. maybe something mechanical, it shouldn't take 100 percent duty cycles to run 10lbs of boost at redline.
The boost can be explained. It's not running full boost at redline so it won't blow up the engine! Lol. I looked at the stock ROM as well, and it should taper lower boost near redline. My 06 STi did the same w/ a COBB Stage 2 map.

Is the WGDC really maxing out? I see it at 80% +/- at the most. Not 100%.

Yes it is running lean thus knocking. Question, where are you reading the peak torque timing?

I can't find any vacuum leak. The car idle's fine ad when I spray carb cleaner or soapy water, I don't find anything.

Should I be concerned about A/F Learning #1? From what I learned is that optimal power through open loop should be 11-12.5 during WOT. I see it tapers down to 6....what does that mean?
