I'm in the same boat - just got the code two days ago, but I've been too busy to post about it since I hadn't combed the net for an answer yet (search first

). My car bogs down when I go WOT uphill, 80-100mph, but only occasionally. I thought it was the plugs and was going to swap them out, but then this 2A9A popped up. Bump for a solution.

*edit: I get 3100 "boost-pressure control, deactivation" also like OP.
