So it would appear the consensus is that this scoop doesn't do any good which actually makes sense. I was wondering how moving more air through the throttle body would affect the fuel-air ratio. It would make sense that if you increase the airflow without having the computer adjust the fuel mixture that the engine would then be running lean, so the computer would have to adjust the fuel to bring the fuel-air mixture back to where it should be. That would have to decrease the mileage. Does this make sense?
You are correct it does not work.
As for the computer you are correct few changes would amount to much with out adjustments to the closed loop system. While this system was thought to be more consistent the lack of the Mass Air meter just kills the read on adjustment.
Now the MPG would matter to how much you adjust the system and what changes. Generally more power in most but not all cases takes more fuel and will effect MPG unless you really make some major changes in other areas.
