Fuel/MPG at various RPM's

[BLACKRAM]

Maybe someone has the answer to this situation. I notice when I set the cruise at about 70 mph (1850 rpm), my pyro reads 750-800. When I raise the cruise speed to 75 mph (1950 rpm) the pyro reads 650-700. These are all level ground no-load situations. I know the higher rpms and thus airflow will carry away the heat faster, but am I getting the same mpg?

Your boost relates more to mpgs than your EGTs. The lower the better.

Wind load will have the most effect. The faster you go, the greater the wind loading, the worse the mileage!
