On a single turbo setup, what should be done about running a vacuum line to the oil inection system? On the stock setup, If I recall corectly it is taken from one of the turbo inlets. What happens if there is no vacuum line?

You're talking about the stock oil injectors right? You most likely need a vacuum source for them to function properly. I heard they need equal pressure across each other and some other stuff i can't recall. You could just plug those lines into a vacuum source past the TB.

thats how you are supposed to do it, but my friends single turbo (apexi) didnt like it that way, it wanted just to be in open air
