FC Intake manifold Vacuum ports :S???
What do these do?
Can I just block them in an aftermarket fitment?
I also posted this thread in the megasquirt section, because thats my ecu of choice.
So far I've been told the angled barb is for the FPR vacuum source, and that the other fatter ports are for aeration near the injectors to improve atomisation.
Anyone have anything to add?

bottom is injector bleed...you might want that one.
edit, and that appears to be s5 iirc. so where the vac lines are at the secondaries is sec. injector bleed. That is also helpful to retain.
