ok so last night my car decided to make an interesting whirring noise whenever I was on the boost, and it only put out about 3psi instead of the usual 5-6psi...any ideas what it might be?
 
check all your connections going to the turbo (vacuum line and oil line) and check to see if there's any shaft play to start off with.
