Its a forge splitter, its pretty well known. You can adjust spring tension which correlates into boost retention. You can also run full divert, full vent and a set ratio split of the two.

The spring adjustment is to control how much vacuum is needed to open the valve and how quickly the valve closes. It also helps offset for any pressure drop caused by a FMIC.

*sigh* This is what I've been asking! Have you tried adjusting it to full diverter to see if the noise goes away?

No, I've just kinda ignored it. Haven't heard the loud resonance and the chattering valve I thought I heard has seemed to die down as well.
