 George,
 I had the L-IV-P that had the GAMI Injectors installed at your shop in
mid-March of this year.
 1 - I have the 8:5:1 pistons;
 2 - WOT, full rich, 2700 TIT's right at or below 1300
 3 - Redline MP is set at 36.5"
 4 - timing 22d TDC
 82 hours on engine, and yes your right, Jack McAllister is a great source on
this engine and has helped me tremendously as has John Deakin.
 Here are the numbers I  fly at, Jack gave them to me but I must admit, I am
still confused why a higher MP setting is not used for cruise
 Take-off - 36.5 @ 2700 (full power)
 climb - 33" @ 2600 rpm
 cruise 29" 2500 RPM @ 16.5 GPH - It should be noted that while I do not want
to speak for Jack, he actually reduces the MP setting for cruise to 27", goes
50 degree LOP and then increases the MP back to 29"  John Deakin described
this to me as the "add back" feature, told me not to worry about it.
 What I cannot answer, (hopefully you can George), is why not a higher MP
setting for cruise?  Is it because the max MP setting for this engine is 36.5"
so 29" MP cruise is to 36.5  as 32" is to 38.5", Continental's max MP?
 Thanks
 Craig
