Default in theory...

If I was to increase the capability of my fuel system without also increasing the demands placed upon it, that would in theory make it easier for my engine to operate thereby increasing efficiency?

no in short. If your injectors/fuel system are near being maxed out, for instance fuel injectors at a duty cycle as high as 90% or more, or your fuel pump not sized properly for your setup and your fuel pressure dropping off at high rpm.

if you better atomize the fuel when its injected you would increase efficiency.

No, the PCM is going to inject only as much fuel as is needed (as determined by the air/fuel tables in the tune)... the rest of the fuel will be dumped back in the tank by the fuel pressure regulator.

To increase the efficiency of the engine you have to increase the airflow thru it.

basics... an engine is an air pump. change out the cam, change out the heads, it will flow more.
