I'm with Dave on this one.  You want the smoothest MAP source possible, and
that will mean connecting all 3 ports, or perhaps just finding the one that
works best.  I'm still working on this too.  On my latest intake, controller
A would run fine (using a port on one of the TWM barrels), but controller B
wouldn't run below about 2000 rpm (using the other port on the TWM).  I
connected the two ports with a T, and not both idle just the same, which may
not be as smooth as A was before I joined the lines.  Eventually, I'll get
around to tying both controllers to one TWM port at a time.   Another odd thought I had was to possibly put a small vacuum reservoir in
the MAP port line, for the purpose of smoothing out the pulses some.
