Is the fuel rate measured in cubic millimeters per revolution?

I thought it was per cylinder per ignition event.

Idle, full throttle?

GMs term is per stroke. Max for the DS4 is about 83mm3 with a hot chip/reflash.

 

[DavidPhillips]

So it is the amount of fuel actually injected into each cylinder at each power stroke.

Correct.
