I seem to have just the opposite problem.
With WOT I have no problem seeing 30-31"MAP whatever
is the pressure of the day.
My problem is at idle I never seem to get less than 15" MAP. This would mean that I will always be running in staged mode with both injector set operating because Tracy set the staging point at 15". I know that this is adjustable but I'm wondering why I can't get <15"MAP.
Has anyone recorded a table of RPM vs. MAP for the range of 1000RPM-6000RPM?
I'm especially interested in the low end and would appreciate any input from our more experienced rotorheads.

I have a fairly radically ported NA 12A (car) and usually idle (1000-1100 rpm) at just under 15" (43-48 kPa). If I set idle at, say, 1500 or so, my MAP is below 40 kPa (13"?), easily. If you're idling where most aircraft rotaries are (>1400 or so? ) you may have a leak in the manifold->sensor line, really bad apex seals, bad soft/firmware calibration or ... etc.?
