bypass valve vs blowoff valve

[chitwnsazn]

Just finished the turbo install and the car is running yet untuned. I'm using an HKS racing bypass valve vented to atmosphere and was wondering if that in possible with a bypass valve. Is it correct that a bypass valve is open at idle and closes when it detects positive pressure where as a blow off valve is always closed until the throttle plate closes and is made to vent into the atmoshere? I'm asking this because I'm not sure which vacuum port on the bypass valve to use (there are two on the racing bypass valve). Also, I'm stalling sometimes and have my maf placed between the bypass valve and tb. Perfect idle though

Thanks

that's why i pmed you about recirculating. I have it set up right now how you told me to but obviosuly at idle it's sucking in air at idle since It's left opend right now. Also, my maf is located between the bypass valve and tb so no stalling issues...
