It doesn't work so well with an atmospheric BOV as in this car. This is especially the case with very large injectors as they are more sensitive to inaccurate air flow metering and fueling.
I see this issue a lot with Tial BOV's and most people end up running too stiff of a spring in them to keep the BOV closed at idle. This of course results in excessive compressor surge. A properly set up Tial BOV will usually be slightly open at idle... which of course will not work at all with a draw-through MAF.
