wide open throttle
any mods?
and hearing a vacuum leak takes skill or its HUGE, i bet you are just hearing your intake

If your boost pressure is lower than previously... likely the BCS is not allowing the bleed off that allows the BCA to open fully.

one of my friends said the boost solenoid could be going bad, the filter thing is falling apart. i looked online and i cant find any. is there like a special name for it?

Yup..it's a bcs aka Boost Control Soleniod.

GM Typhoon 3-Port Boost Controller Solenoids from HorsepowerFreaks

Nope. Walk out to your car adn take the part number off yours. Then search on that. It's like $30-40 dealership.
