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) Carl Cadwell, N25CL
