Sounds like spark blow-out or rev limiter. What's the plug gap set to?

Do you have a blowoff valve? Do you see boost bouncing when its doing the issue?

If you're making 2psi then your wastegate line is NOT collapsing. It will have pressure in it at that point. Have you checked your wastegate/s for binding? I had a wastegate that would stick open intermittently and keep my boost around 2-3psi. I lubed the shaft with anti seize and it fixed the problem.

If it was sticking would it make that sound ? Thanks I'll check it...
