Help with STI Turbo whine!!???!!??

A friend of mine just stopped by my house 2 have me listen 2 his 05 STI... he said after messin around with a talon on the highway last night his car has been whining like a supercharger..... but only under boost....so i go 4 a ride with him and there is no noise @ idle or part throttle driving around... but as soon as it build over 6psi it whines really loud (in cabin) and spools up to 17psi fine, no lack of power or loss of vacuum @ idle... and its not burning oil... any1 have any input?? my next step would be to check bearing free play in his turbo.
