Old Jupiter - I don't think anyone is trying to make more power, but would expect to have less power. It's just an inert gas that you make your own supply of. By adding an inert gas, you then draw in less air, and require less fuel by the same ratio of fresh air you are able to displace. From a fuel efficiency stand point, egr makes your engine act like a smaller displacement engine
