Banks Intake and exhaust system

Simple gasoline engine air/fuel stoichiometry says you need 14.7 lbs of air to 1 lb. of fuel. If you add more air, then you need to add more fuel or you will generate a lean condition which will raise exhaust gas temperatures and eventually cause engine damage. If you add more fuel than necessary, then you generate a rich condition which wastes fuel and reduces mileage. Engineers/chemists know this. I guess the rules of mathematics and chemistry don't apply to everyone else.
