The flutter doesnt bother be but its not for everyone.

Make sure you get with your tuner on what spring to run. Im running about .1bar to light but I experience almost NO taper.

Make full boost (19.5psi) @2700rpm also =D (VF52)

FYI, my EWG never fluttered like that. It was rock solid holding 19 or 20psi to redline on an evo316g and I only very briefly used the hybrid setup. 3 port BCS and there should be no fluttering if it's tuned properly. 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.
