Whining noise from stock turbo!

When my truck is cold in the mornings when my turbo spools up it also makes a whining sound. I notice it does it more when I have the smarty tuned up on higher setting but does it no matter what usually. Is this an indication my turbo is going bad.??
Haven't seem any oil leaks around it nor do I have any boost leaks...

I think I know what you're talking about. It almost sounds like a humming sound. I only notice it for a couple blocks then it goes away.
