Turbo singing @ idle

I have heard a 7.3 PDS (96 ish) with an audible whistle of the turbo around town and at idle.. How is this achieved? I own a 97F250 pretty much stock except for a Banks Git-kit and K&N replacement air filter. Thank you, Chris

Bigger exhaust gutted cat

My idle isn't as high as some, but the gutted kitty and 3" down pipe, more open exhaust will do that on the OBS trucks. Turbo modifications also do this, but i've not got the deep pockets that some have..

ive got a 96 psd and mine sings you can almost hear the turbo over the truck. The only thing i have is a k&n intake a 3in downpipe and a 4 inch straight pipe turned out in front of the rear tire. the turbo whistles at an idle and when you shut the truck off you can hear the turbo slow down and stop spinning. It also purges loud if i bring it up to 3000 rpm and let off.
