No, There absolutely are things you can do which improve both low RPM part throttle efficiency and WOT.

More open intake. Decent fuel injection. Higher compression combined with more cam overlap. Long, tuned intake tracts. 4 valve heads.

Go look at Honda Civic engines. Amazingly powerful, amazingly efficient.
