Ah, yes I remember a thread about the chip. Nope, not making a point. I am skeptical about the chips, but the fuel and ignition curves can be created to change the characteristics of a motor, and even possibly increase power either in certain ranges or across the board. Ignition/fuel programming is probably similar to cam designing, the perfect cam hasn't necessarily been designed for each situation, but lots of really good cams have. The oil analogy is just silly.
