I will be buying brand new. Do they come flow matched or do u have to take them somewhere to get it done. I wouldnt have a clue as to who does that sort of thing. Any assistance would be great!

To flow match 1 set would involve drilling the smaller flow injectors to match the largest injector.

The matched sets are then on sold to resellers Link to comment https://www.fordxr6turbo.com/forum/topic/61492-bosch-968s/#findComment-934385 Share on other sites More sharing options...

Because the air distribution to each cylinder is different, amongst other variations including dynamic and static compression, it's a numb debate.

Because the air distribution to each cylinder is different, amongst other variations including dynamic and static compression, it's a numb debate.How many people go this far in flow matching individual cylinders? Surely it will be quite normal to just flow match the injectors and leave it at that or is there far more to it?
