Nothing the dealership did really fixed my issue. So I just happened to get stuck working like a madman and I was finally able to install my hotpipes tonight that I ordered like 2mos ago.
First test drive, the crazy whiney whistley sound is gone when I accelerate, pretty sure my factory ford pipes were bullshit. I have to do some data logging to confirm, but 99% sure the ecopower hotpipes just fixed my boost leak. I did the tial BOV option too, so could have also been factory BOV idk, but that s*** is in a box! don't think its ever going back on.
