Default I have a strange honking noise coming from (I think) my intake...
It happens only when boost reaches about 0 on my gauge. The noise sounds almost like someone blowing over the top of an empty beer bottle. I cant figure out what the hell it causing it. Maybe my DV? But like I said...it only happend at about 0 boost. Any thoughts?

Default
there's a good chance it's the DV diaphragm failing to open and close properly

Default Thats what I thought at first...but why only at 0 boost? On the highway..
I can make the noise happen constantly..in 5th gear. Maybe I'll get a new DV. Any other ideas?

0 lbs would be where it's switching from closed to open

Default there is a pressure loss across the I/C
while your guage is getting a reading of 0 @ the intake manifold, there is more pressure in front of the I/C where is BPV is located
