I think you don't understand what Duty Cycle means. Duty Cycle is a value that tells you the amount of time the injector is open when compared the amount of time it takes the engine to complete a revolution. That time will vary with each RPM. A lower duty cycle only tells you that the injector is opening very little time, which is a good thing. So to paraphrase your statement,
To lower the duty cycle, you need bigger injectors.
With that in mind, from your statement, what that means is, to be at 80% duty cycle you need 640 cc injectors and to be at 65% duty cycle, you need 787 cc injectors. And again, those numbers do not apply to us because the DI system injects fuel at a high pressure, and takes the bulk of work off of the port injectors.
