I was wondering if anyone adjusted the allen wrench screw on their APS BOV.

The nut that screws on top of it out of the box was really loose and basically at the top. I ended up screwing in the screw more, making the spring more stiff.

It didn't seem to be fluttering or surging, but have any of you messed with the adjustments of this BOV or just left it at the height it came in? Just curious what it changes. I'm guessing if its too loose I'd be leakin boost..

 

Try setting the adjuster four-five turns out, and lock it down. The APS bov is normally set from the factory. If it flutters, it's probably mounted backwards, and not doing it's job.
