Following on from the "low boost" discussion, I have added a few columns to the table provided in the M14P maintenance manual and that enhanced table can be found here: http://bit.ly/M14P-fuel-consumption
Note that Po is atmospheric pressure and, as Dennis points out, that is 760 mmHg at STP (sea level). With the engine off, the MP gauge should read atmospheric pressure, a point only obvious to me after it was pointed out!
The supercharger on the M14P, according to this table, provides max 125 mmHg boost at max RPM. This is only 5 inches boost in USA/imperial units.

Very well done!
For anyone who is interested, here is the link on my web site which may make understanding the M14 power chart a little clearer. http://www.yak-52.com/Power%20Settings.htm

If I had known about your chart I wouldn't have had to do anything at all!
