Tracy,
 
I reset the EC2 to the "RV-Otter" settings (cold start on), and it is very close now.  Got rid of most of the staging stutter too!
 
Now a question about oil pressure for the group.  Since I removed the balls and springs from the rotor jets and have stock jets, here are my oil pressure readings.  Somebody let me know if this looks like enough flow.
 
Cruising at 5350 RPM,
 
Oil Temp     Oil Pressure
160                86
195                75
201                70
 
and at idle RPM with Oil Temp at 170,
 
RPM         Oil Pressure
1250              19
2000              37

In the mean time, I suggest 16 - 17" Hg for staging point.  Yes, changing staging point means you have to re-do the map table in this area.   In the mean time, If you are having this surge and have an EM2,  step to the map entry just above the staging point and richen it and the next two about 30 - 40. 
 
This problem is usually caused by the engine going lean right after the staging point.   You can do it without an EM2 but it requires a bit of finesse.   Turning up the mixture control will also eliminate the surge but the engine will probably be running rich under the staging point.

Bill,
If/when you find a solution to the annoying surge during high idle/taxi
let us all know what it is.
I too am experiencing this annoyance.
I think we need to set the staging point higher but have not tried this yet.

Now that the engine is running correctly again, I have to start all over again programming my EC2!  That nasty crossover point at 15"  MAP is giving me an annoying surge at a high idle (taxi) speed.  Hope a close reading of my manual will let me sort that out.
