yeah my bov is HKS SSQV, its vent to atmosphere..thats why i get so much stalling problem, but recently I found a way to drive properly..LOL

i tried to avoid putting on gear neutral especially do not put it neutral when the car is still moving or rolling even though you were about to stop. Wait til its fully stop i guess.....

anyhow im gonna go for recirculation kit, hope that'd help, wouldnt it?

 

The stock BOV does make a decent blow-off sound if you have an open-element air filter (Buschur, RMR, etc.).
