Yes, yes, yes. Heard something like that before. I'm not going to claim it works either, I've never seen it happen. I'm in fact not a believer. But the idea really interests me. Enough so that when I hit this article it made me think maybe there was a small amount of truth to it? These guys were adding hydrogen and running much much leaner than otherwise possible. It's not a matter of conservation of energy being violated. It works because you're simply using chemistry to run leaner and get better mpg. I haven't seen it work. But don't dismiss it out of hand.
