Engine Bogging under boost

Hey guys,

First, let me say that it rained ALOT during this past three hour trip with my car.

Anyway, the car seemed fine and had been fine the day before. This morning I took this three hour (mostly highway) trip through the rain, and on the way home the car bogged BAD anytime boost was upwards of 10 psi. Running any other way, it is fine. Pulled 33 mpg actually.

No CEL. What could be up?

Maybe something to do with the really moist air?

I hope so. Or some moisture sucked up somehow.

Also, I turned Comp mode on to make sure it wasn't the traction control holding back.
