Not sure i get what you mean? 100 percent equal flowing?? all injectors will flow equally in the same rail? plus if you waited until you got the chip it would take ten mins to change the injectors, its a really easy job, and it would save fucking your engine by bore washing it with a rich mixture for the next few months. It has no advantage to use higher flow rate injectors and then effectivly derate them by turning the pressure down, effectivly making them the same flow rate as the originals, it gives you no more overhead of fuel and no performace advantage.
