Stock uses a bypass valve. They do make swooshy noises. Do you have an aftermarket air filter? Mine definitely got louder when I removed the air filter box.

It is the small diaphragm looking thing between the 3000 pipe and the accordion hose off the turbo. It has a vacuum hose to it as well.

you shouldnt really hear a LOUD woosh. lol make sure your couplers leading off the accordion hose and the inter cooler are tight. including the throttle plate pipe.

its not so much its loud i can just hear it at night really only. but i know my intake hose is trashed and thrashed real bad. and i know i have a huge boost leak cause i cant hold max boost for anything. hense for me getting an intercooler kit for my car my stock piping is all messed up for the guy who owned it before me.
