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.

Greetings,
I've taken up enough of Tracy's time on the phone today, so I figured I'd post this to the list, and he (or anyone else) can comment.
As I mentioned, my MAP reading is only 27 on the ground, at full throttle.
