Are you guys factoring in the return to tank fuel for the Continental engine? 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:

 

1. 17,570’ pressure altitude; 20,090’ density altitude; 2490 RPM; 29.5” MP; 195 KIAS; Indicated Fuel Flow 18.9 GPH
2. 17,430’ pressure altitude; 20,310’ density altitude; 2510 RPM; 27.1” MP; 193 KIAS; Indicated Fuel Flow 19.1 GPH
3. 16,500’ pressure altitude; 19,090’ density altitude; 2490 RPM; 27.5” MP; 195 KIAS; Indicated Fuel Flow 19.0 GPH
4. 10,510’ pressure altitude; 11,510’ density altitude; 2490 RPM; 29.6’ MP; 207 KIAS; Indicated Fuel Flow 18.8 GPH

      5.     5,050’ pressure altitude;                                     2900 RPM; 60.0”MP; 295 KIAS; indicated Fuel Flow 70.0 GPH
