I currently have nothing going from the PCV valve,
There's your issue!
You need that pcv working and in order for it to work it needs a vacuum source when butterflies are shut.
That allows the valve to open under vacuum from throttle bodies (without that it remains shut which means you only haver one breather active which is not enough.
At other end one part of T should go to induction pipe so when turbo spools it draws spent gases from the rc.
Put it back to stock type pipework and all hopefully all will be good
