Nottin' like boost...

i hear a hissing noise at idle, i looked at the vacuum line that goes to the boost controller and that looks fine considering its a new silicone line, and i looked at the boost gauge line, both dont seem to be making the noise but i still hear a hissing sound

the weird thing is though as soon as i give it some gas it goes away, also when i have the ac on and the car revs itself up it also goes away

during the hissing sound my vacuum is like 11 which is quite low to what i am use to but when it revs up a little and the noise stops it gets to about 15

what can this be?
