STINGRAY 70, You are correct. The GAV does effect the AFR at all speeds except idle.

Also, when pulling a long hill, richening the mixture slightly will increase power a little and lower the coolant temperature, Just like an airplane.

Open the GAV a little when the engine is cold and close it down when it warms up.
