For some vehicles, there is more flexibility in this imposed MPG limit. The ECU is limited in its ability to provide greater MPG than is specified on the window sticker.
If you can successfully supercede the imposed MPG limit and keep the emission feedback system unaltered, you are in a winning situation.

I'm not following what you are asserting. Please be more explicit.
I know for instance that certain tuners allow a diesel engine to run more efficiently, but that comes at the cost of emissions compliance. Heck, we've now got particulate traps that simply burn fuel to generate heat to vaporize those particulates. That's an inefficient process.
There is no such thing as imposed MPG limit. Nobody and nothing stands between a driver and any MPG they wish to strive for.
