Your confusing atomization with intensity, a quality nozzle with quality orifice finish will atomize very well even at 200BAR.

Idle smoke is usually caused by the nozzle type and/or cone angle. Opening pressure set too high will do as you said earlier; cause loping and stalling issues. The fact of the matter is the higher the opening pressure, the duration event is shortened and overall less fuel is injected.
