Maybe that wasn't as clear as it could be, probably you figured out what I meant, but I can say this more precisely, and I didn't mean to imply that DCD burns lean, which was the conclusion of #243.
What I meant was:
Fuel input has not changed since we started DCD. Produced work has not changed. The number of cylinders experiencing pumping loss has not changed. But manifold pressure has gone up, manifold vacuum has gone down, pumping loss has gone down.
And this means available work has gone up.
