Default Whistle sound at 3200 rpm????

Under any type of acceleration there is a slight whistle sound at about 3200 rpm. No mods to the engine except it is chipped. It almost sounds like a valve letting air out or something?? Just wondering if that is normal or what it would be. Thanks!!

Default It comes from the turbo when its cold I believe....

I also think it's when the turbo's at maximum efficiency

Default Hm... well it does it when its warm. I dont drive it when the turbo is still cold.

It sounds like it is coming from the left side of the car. The opposite of the turbo. Maybe like a belt or pulley???

If one is ripped is it doing anything bad? I know nothing is good when its ripped but is it?

No CEL even though you feel all this extra HP came back. Shoot looks like I'm gonna go looking for some ripped L hose....

Where was this hose?
