changing anything in it, either we increase, or we decrease, consumption, taking the opposite direction to that which increases !!!
Mathematical evidence, when the derivative according to a parameter is not zero outside the maximum !!
It works as well for adding water as for modifying the programmer or anything in the engine !!

common sense !!
With the same motor, by changing anything in the motor, we always move further away from the maximum of the curve. the majority of the organs are already optimized with respect to each other for the powerful version, we can only lower the various yields most of the time. If the camshaft is designed to deliver the maximum torque to you at one speed and you operate at another, your gas passages, valve diameters lengths and diameters of conduits, resonances, operating temperatures etc, everything is shifted, the couple will never be optimal and everything has to be started again.
On the other hand by just modifying the parameters which have been intentionally degraded by Opel (and other manufacturers who use this old string) advance to ignition, advance to injection (multi-injections), richness and other EGR valves to control pollution , we can get to the top of the curve (derivative) you are talking about.
