Wastegate going apeshit w/ video

Talked to FM about getting the upgrade wastegate setup but they didn't seem 100% sure this would solve my problem. Once it comes in we'll see but I've got a feeling it might not. Thoughts?

and how can you tell your wastegate does anything with no load on the motor?

Your video looked like from the view of a badger poking around in a whole or something, very annoying lol, im guessing you talking about the noise its making?

Was it still doing it when you held it?

Yeah sorry about the video. I was trying to vary the location to demonstrate where the noise was loudest. When I held it the noise was much much quieter. I just noticed some other BMWs videos on youtube that have the same exact thing.

It is a loose flapper. Or at least something causing the flapper to be loose. How would one fix that?

Ratchet parties, i've had a few of those in my days

Edit: I'm guessing your WG is non-adjustable?

What, you don't like my custom rain gutter exhaust?

Are you really judging my exhaust from some shakey *** video from a 12 year old camcorder?

Yes, still makes the noise and over-boosts.

Negative. I figured I'd replace that wastegate actuator once it arrives and if the problem persists then I'll crack it open and take a look.

was the flapper loose when you had the turbo off? Is the rod adjust too far out? (I bet it is at 6psi)

I should have said this before, when I tightened the rod before it didn't make the sound stop, but it was quieter. Still present though. I went back out and tinkered with it more and noticed there's a couple millimeters of vertical play on that exterior flapper tab. The ***** loosey goosey.
