Are the numbers you are listing the indicated fuel flow or the corrected ( actual ) fuel flow? It has been my experience that the difference between indicated fuel flow and actual fuel flow ( based on fuel burned ) is about 1 GPH. My TSIO powered Legacy: - 17,570’ pressure altitude; 20,090’ density altitude; 2490 RPM; 29.5” MP; 195 KIAS; Indicated Fuel Flow 18.9 GPH

- 16,500’ pressure altitude; 19,090’ density altitude; 2490 RPM; 27.5” MP; 195 KIAS; Indicated Fuel Flow 19.0 GPH
- 10,510’ pressure altitude; 11,510’ density altitude; 2490 RPM; 29.6’ MP; 207 KIAS; Indicated Fuel Flow 18.8 GPH
