The stock turbo dynamics is way too aggressive for an ewg. It's something like
-7 - 5 - 3 - 1 0 +1 +3 +5 +7

It should be something like

-1 - 0.78 - 0.56 - 0.32 0 +0.32 +0.56 +0.78 +1

That way the ecu is using smaller percentage increments to control the boost. This is how you get rid of that flutter.

I'm posting from my phone so I hope that shows up properly and makes sense
Yea that's what I meant, I just worded it kinda funky

Makes perfect sense though. I can't wait to see the video, provided you find it later. I am going to run a hybrid setup for more reasons than just the flutter, but it'd still be pretty neato to see an EBCS + EWG with no flutter.
