My car did that for about a month and i thought my turbo was going out. Then one day it just stopped and it has not made that noise since.

Two things can be happening here. One is that you have oil coming in from the relief valve that is connected from the valve cover onto the intake (most likely and normal, but unwanted), the second is a bad turbo seal. Remember that the turbo uses oil that comes from the filter area and then drains into the pan.

Something seems to be missing here or you have a bad center cartridge.
It sounds like poor oil flow to the turbo to me. That's the only thing that makes sense, since you stated that the squeal goes away after the car is warmed up. If you want to keep what you have at the moment Seafoam your oil to try and remove any caked up oil in the center cartridge or just buy the 16G variant like you stated in your other post. If you have the original T25, you may want to consider the upgrade of a 16g...but don't forget to support it before you go turning up any boost.
