Maintenance/Repairs

Recently when under normal acceleration I now get a loud sound until I get to cruise speed or let off the gas. It can best be described as a fog horn sound or very similar to the sound you get when blowing over the lip of an empty beer bottle. It is a constant sound that does not vary in tone with RPM and does not seem to be drive line related but more engine/intake/turbo related in my opinion. It does not happen under very light acceleration, disappears as you get to cruise speed (or let off the gas), and to me does not sound mechanical (no grinding, clicking, banging, rattling sounds).

I wanted to see if anyone here has encounter this issue and see what was the solution.
