There can be multiple options.. You need to make sure your fuel mixture is proper and not killing itself out. Once you have determined that issue, process of elimination is your next step...

To start off, make sure the MAF is plugged in completely. That's what happens IIRC if it is unplugged. If it's that, easy fix, otherwise get that ruled out.

Then check for large air or exhaust leaks you could have made installing the new turbo. That's all you changed right?

Probly just a big ass boost leak.

+1 on makin sure the MAF is plugged back in. Make sure everything is tight after you warm the car up. After a installing a turbo you will usually find you need to re tighten the manifold nuts. Do a boost leak test.
