Are there any negative effects with aftermarket BOVs? Yes.

Additionally, the lack of recirculated air can cause the compressor/turbine wheels to stall between shifts and it takes longer to build up boost again after each shift.
Wrong. As long as it vents the wheel wont stall. Not venting at all is what will cause compressor stall. The vented air goes in BEFore the throttle body, on a side that is open to the atmosphere anyway (it goes into the intake, which has a big hole on teh end with the filter on it) The air vented back into the intake is nothing more than additional normal air.

At least the way I am reading that statement its wrong.

AWESOME info post though
