Phil,
We run LOP.  The first 150 hours were with TCM injectors.  GAMI
injectors for the last 50.  I fly 2400 rpm and 29.5" MP.  I fly between
FL 140 to 250 and typically FL 240 and 250 on flights longer than 1
hour.  VM1000 engine monitor.
  
I could only pull the hottest cylinder back to about 1540 - 1550 EGT
with TCM.  I can pull back the GAMI to about 1520-30 (100 LOP).  Peak is
about 1630.     LOP temperature spreads across the cylinders are similar to yours with
both with TCM and GAMI injectors. The coolest one is 1440.  The fuel
flow varies from about 15.5 to 16.2 gph depending on the altitude.
  
After installing the GAMI injectors, the cylinders all peak at
approximately the same fuel flow of 18.3-18.5 gph.  The cylinder head
temperatures vary from 292 to 312 at 8,000 at 4 degree C.  At FL 250 and
-20C they run about 270- 290.
  
My turbine inlet temperature (1530-1540) is typically the same or a few
degrees higher than my hottest cylinder EGT (1520-1530)
