I found a pretty good deal on the HKS bov and I wanted to try it out. I don't know the quality of the ZAGE bov, and supposedly the HKS bov helps out with performance.

However, unlike most people, I'm not really a fan of the high pitched noise the HKS bov makes.

there's no way a BOV can improve performance unless the BOV you're currently using is malfunctioning. but a good deal is a good deal, go for it! what will you have to do to modify to make it work?

^ We both believe the Zage BOV isn't working correctly and is still allowing compressor surge to happen.

Hey Peter, where did you mount your meth tank?

so you don't think the bypass valve is opening fully on throttle-lift?

isn't the whole idea of a recirculating valve to help prevent compressor surge?

Unplug the line from the bov and hook it up to a boost gauge to make sure you are getting vacuum when you lift off.

you should have vacuum at idle, no need to hook up a boost gauge, just unhook it and stick your finger over it while the engine is idling. you should feel if you have vacuum. is the vacuum line hooked up to the correct side of the throttle body?

If the vacuum line is hooked up to the wrong side of the throttle body, you will still have vacuum at idle though.
