| We know that after the BOV releases the previously measured air into the atmosphere that the mixture is rich for a moment afterwards. 2 things can cause a rich mixture- more fuel than normal, or less air than normal. Do you think the action of releasing the air into the atmoshere makes the injectors inject more fuel than they normally would? Or do you think that they inject the same amount as they always do, but there's just less air to go with it? I think that the ECU is telling them to inject the normal amount of fuel that it always has. Only now there's less air to go with that fuel, causing a rich mixture. In the end, the engine did not burn more fuel than normal, it just mixed that fuel with less air than normal. Based on that, I don't think it changes fuel consumption at all.
