I would take a video, but I'm removing it tonight. The sound is not to my liking; so I'm going back to the stock BPV.

These systems for the s54 (this one and the ESS kits) are mafless right?

...or is the buildup of pressure just regulated by the engine rpm?
Yes, opens by vacuum; bolted to the bottom of the manifold. The VF kit is MAFless, not sure about the ESS kit. Pressure is dependent on the engine rpm (assuming your talking about boost).
