Based on your knowledge of other (std) TSIO-550’s, do you believe your 21 GPH to be approx the same, better, or worst economy?


One would have to have a pretty high MP and rpm to get the mass airflow adequate to be far enough LOP for 21 gph to be a usable mixture.

A more reasonable LOP cruise FF on that engine would be 17 gph or so while keeping TIT under control.
