noise

[midospike]

I was driving the other day.. stopped to get gas. Started the truck back up. I have this loud vacum sound now? Coming below or by the exhaust/turbo. Boost is good, sound is there when idl and a little louder until i have boost. the noise goes away? Once i hit 0 psi on the boost gauge the sound is gone? I think i have a vacum leak? What else could it be? Strange thing is it just started i feel for no reason? any ideas? what to look for? thanks

Does it sound like a giant vacuum cleaner?

high pitch whine. I can hear it at idl and until 0 psi is reached. After that the noise goes away or fades. I have notice no difference in gas performace or running performace. Just a loud pitch whine.

My orange rubber elbow for the intake came loose from the turbo once. All the turbo noise was much louder... Is that a possibility?
