I take it you have a boost gauge correct? If so, what are you boosting? Are you running the little crappy stock bypass valve? You say you here it?... are you talking about the turkey? because you can not hear the stock bypass valve... all it does is recirc air, it is not atmospheric.
The very simple first thing to do is go to your local Advanced Auto or whatever parts store you have and get new vaccum lines for your turbo and intake. Get about 3 feet of 3/16" and about 3 feet of 1/4 fuel line (it has cloth reinforcements in it). Look at the bottom side of the wastegate coming off the turbo and you will see where the stock vaccum line is attached with a little crappy 90 degree connector. Pull that off and trace that line up to your intake manifold. Pull that off as well. All of that needs to be replaced. When I did mine, the intake manifold seemed to be a little smaller in size which I why I tell you to get the 2 sizes of line. I would also grab a 3/16 to 1/4 barbed reducer just in case you need it. This line is very simple to replace. Keep in mind... YOUR CONNECTIONS MUST BE TIGHT AND SEMI-HARD TO GET ON or you have the possibility of a vaccum leak. I have a manual boost controller and I thought I put everything on tight and I still had a leak so it can happen. I could hear mine though and was able to find it easily.
There are other places that leaks can occur also... which would be your hard pipes or stock pipes etc... obviously you already know the stock plastic ones crack easily.
One other thing it could be is your wastegate actuator. A friend of mine local here with an MSP had this issue. His would idle like crap etc and we can actually hear his wastegate leaking so it is going in the shop this week to hopefully get replaced under warranty.
...also check the intake pipe connection that is on the turbo to ensure it is seated correctly and tight as well... I don't have pictures for you but if you need them I would be glad to walk outside and snap a few...
Hope this helps... this is all taken from my personal experience... been there done that type crap... (cool)
ok.. i dont have a boost gauge.. and im at stock boost and i have the stock bpv!! what i hear is the turkey and the other thing i hear sounds like air leaking or being sucked in.. it sounds real weird.. but what does it sound like if the wastegate acuator is leaking??? and im sure a few pics could help
