Vacuum sound, possible hose leak?
The past couple weeks have been the first real opportunity to drive with the windows down, and I've noticed a sound I did not hear before. When I get on the gas enough for the turbo to spool, I hear a vacuum-like sucking sound. I don't know if it was present before, I haven't had it in the summer. It doesn't sound like any air intake i've heard before, and I've had a full fipk k & n on a tacoma that was loud as ****. I'm just wondering if I have a leaking hose somewhere or if it's a normal sound. It honestly sounds like a loud sucking of air thru a straw.

high vacuum at idle
you would probably not hear a vacuum leak except at idle. If you had a turbo boost leak then you would hear it when you put your foot down.
A soft higher pitched whoosh sound I hear all the time from my 225Q. It is normal.
