I just ran into that bulletin somewhere on the internet. Sorry I don't have the link. I don't recall where I was.

Woodward is right on. Starving turbos was the issue. The bulletin listed VIN patterns for determining whether you had the filter or not. If I remember right, they dropped the filter for STI's after April of 2005. I don't remember if it was the same for WRX's, though.
