Cal codes are more for smooth idle and economy than power from what I recall and the number I remember is 0.67.
Set the overhead, keep good filters in the fuel system and you are WAY ahead of the average 500HP mill. If you have a "DAVCO" (IMO the only good diesel fuel filter), change it ONLY when the fuel is sitting within 2" of the top and no sooner.
Make SURE the fuel heater, if equipped, is OFF in the warm weather (above 20*F), hot fuel kills your power by lowering the fuel density (fewer BTUs per gallon due to expansion).
