Any reason why a professionally rebuilt T3 should whine like a siren?

Anyone ever heard of a turbo whining initially until broken in?

I finally got everything back together, and I'm afraid to really drive it since the turbo is whining pretty loudly. I replaced the oil supply line and cranked with the injector lines off it to get oil moving before starting it. I let it warm up at idle for 10 min, but then as soon as I revved it I heard some serious whine.

How much play does the shaft have? Check for air and exhaust leaks.

Turbos do not break in.

Crap.. I was afraid you were going to say that.
I leak-checked everything, too. I called down to the rebuilder, who said send it in. He suggests it might be out of balance.
