I was lucky in that I could design my system that had all of the vacuum lines connected into the same manifold, including the ITBs and the IAC. That being said, I actually capped off the IAC line since while I was struggling with the initial tune, as it was another variable. As I have no issue with starting and idle with the current tune, I haven't put it back in. This is a long way of reiterating the potential solution of a vacuum manifold that can fit all of your connections before going to the MAP sensor, rather than doing an allocation hoping for the best.
