Okay, so if the piston on your aftermarket BOV isn't fully covering the whole that the pressure comes out from while boost is on does that mean you're losing boost and power?

Like if on idle you can see the bottom of the piston going up and down leaking

yes you are dong it wrong. screw it right in till it seals. if it is screwed right in and doesn't seal then you need to put shims in. I installed mine today and needed 4 washers to get it closed.

YHi I just purchased a kompact dual port series bov to suit my fg f6. Motor is stock and running .9bar boost. My bov came with a pink spring. I found it was opening way to early causing boost to vent out. I have fitted all 6 supplied washers to spring and retested , it is better but still not holding boost to .9 bar. Do I need a stiffer spring? Or can I put more washers?

I have fixed my issue by removing pink spring and stretching it slightly. I have refitted it with 4 washers. And tightened the valve to the hardest setting then backed it off a little. Sounds great and holding boost as it should.
