Hmm. My understanding of such things from my experience with my various F.I. cars, is that the BOV should be closed at all times, except when there is a pressure differential between the intake manifold and cold pipe, meaning the TB is closed but there's still boost in the cold pipe(s).

If it were open at idle, and you ran an un-recirculated BOV, you'd be sucking unfiltered and unmetered atmospheric air at idle...

I could be completely wrong though. Wouldn't be the first or last time.
