I've found these and the "krank vents". How do you fix the excess pressure from when the car is under boost, when there is no vacuum. I've disconnected the pcv and left both breathers open and it still builds up enough pressure to cause the turbo to puff blue between shifts under boost... I thought I saw a setup a while ago where a guy used a smog pump or something to draw out the air... or am I going crazy?

When under boost, the vacuum source is your turbo inlet tube. That is why from the factory there is a hose going from the side of your valve cover, to your intake tube. That is how it "sucks" out crankcase pressure when under boost.
