FIC sells the same EV14 Bosch injector as a 900cc injector because when tested with gas in the real world they do only flow slightly more than the DW 850s. Many on the boards have posted up about switching from DW850s to ID1000 and not gaining any IDC headroom whatsoever. I guess you can choose to believe the data sheet or you can believe the people on the forums who have actually experienced this issue. Some say its because of the calibration fluid they use to flow test the injectors with. Some use N-heptane and others use gasoline.
