    Recirculating is ultimately what you want, and the stocker is good for upwards of 22PSI or so. When you get tuned, you probably won't get tuned any higher than 20PSI to keep the VF39 reliable and safe. If you plan on going bigger in the future, sure keep it. But if not, you have no need for it and can spend your money on something better or more necessary.

    BOV

    I have a 2002 WRX with only an SPT cat back on it and I like the blow off sound. Can someone please recommend a good BOV to use on the car. I like the Hybrid one I hear they are betting for the car is this true or is a full atmospheric OK to run. I would also like your suggestions on a good one to get also.

    Thanks,


    Eric

    It should be closed at idle. You most likely haven't properly adjusted it.

    BoVs are not install and go. You have to adjust them. That being said, that valve is notorious for leaking.
