This was with a 38mm. I dont remember which spring I had, but it started to crack open around 10psi and was fully open by 14 or 15.

You can really hear it in the video on the top end when it's just roaring. That flutter would drive me crazy though.
Do you happen to have a sound clip of your EWG + EBCS? It would be interesting to see, especially because you have no flutter with only an EBCS.

P.S. You were probably running a 1 Bar spring on that EWG if it opened near ~14psi
