Opening pressure does have an effect on timing, as it takes a finite amount of travel to open the nozzle and there is some compression effect (although minor).
That's why you should set all the nozzles close to the same pressure, whatever it is, when rebuilding, else you may get a rumbling engine at idle due to different opening times. Some engines show this much more than others. Leaking injectors cause much more timing divergence, obviously, so do leaking delivery valves or seals.
