From the little I know - having never done the job yet - you need to set the pressure at which they spray out the fuel. New ones are not balanced they are just assembled. I've just bought some reconditioned ones from a supplier in the UK that balanced them for me. They set the pressure to be slightly higher than the specified (as per the FSM) to allow bedding in.
These are mechanical components that wear and so I guess somewhere there will be a gap that gets bigger as a result of use which in turn I guess will change the pressure at which these things spray.
When I fitted by new reconditioned injectors I also replaced the heat shields which (I have read here) are meant to be a one time fit only - they provide a seal between the injector and the pre-chamber.
