Weird sound when accelerating fast

[werdna]

It's like someone blowing through a pipe. Only occurs when I accelerate really hard. I'm on VitTuned Stage 1, other than that it's pretty much stock. I had a vibrant muffler put in a couple days ago.
Any clue what's causing this noise? Could it be the intake? Or too high boost?

Definitely something is leaking air. Don't go full boost until the situation is taken care of. Especially since you do not know the source of the leak.
However, I would start with your new muffler. Make sure it was installed / secured properly. A single bad weld can cause a leak.

I think there's a leak around my resonator, can hear air blowing out. Will get it checked out with my welder, thank you!
