I'm starting to think this is a fueling issue (read: actual knock, not phantom)... the problem seems to be getting worse. The car just refuses to pull hard under boost. Occasionally it pulls fine, but it seems to be getting more and more rare, and only when its completely warm and has been running a while.

I'm starting to suspect my fuel pump, filter, injectors, etc. I might grab a dummy gauge and see if i'm really lean under boost.
