does ram air affect economy?

Without ram air the area forward of the throttle blades is a given negative pressure, period. With ram air it may not be enough to make positive pressure, but there will be a difference in pressures (negative) on both sides of the throttle blades. Now what happens when there is a pressure difference in two areas and a non sealed wall between them (throttle blades), hmmmm, well naturally they want to equal them selves out, if you argue with that you just plain don't get it.

Just to clarify, I am not asking in reference to air fuel ration, ok, get it? Just if anyone KNOWS if the lower vacuum (closer to zero/ambient) will affect how much the distributor advances at cruise because the affects of a higher pressure from ram air.
