Kinda what I'd like to know. Better Justin has answers
I would think that the vacuum from CAI tubing prior to intake would have much less vacuum than port under intake. Route both there but then you'll have twice the residue on TB blade and IAC as well as intake ports. :dontknow:
From first hand experience don't make the mistake of putting two of the wide open vent tubes in the valve covers. There is a reason that there is a smaller one and a bigger one... Truck ate about 2-3 qtrs of oil in a 2 hour highway cruise because it was sucking oil right out of the valve cover into the intake. I opened the throttle body blade and oil just dumbed out.
