They fabricate a recirculating fitting onto the BOV so that you will not have the stalling problem. The HKS unit will recirculate just like the stock BPV.
Still waiting for mine to arrive, once it does I'll post some pics. Kevin is polishing the BOV and the intercooler so it is taking a little more time than expected. I'll wont install it until the winter is over though because it got pretty cold over here on the east coast.
