I have an in car video of the OEM BPV vented to atmosphere.
You can only vent the OEM valve if you have gotten rid of the AFM.

You can find my video in the center column here:

ceracer33, that is correct. Buyimng a full EMS can correct that as well.

josephah2000, the best performing valve you can have is the OEM or the HKS unit that copies the OEM design.

It will cause the car to run rich UNLESS yoiu reroute it back into the intake. The HKS can be set up either way vent to atmosphere or recirculate.
