injector size and tuning

[02trubluegt]

So I bought a set used of what I was told was 47lb injectors. Then I proceeded to get my tune and load it and go for E85, car runs great and runs fine, now I have a buddy doing essentially same thing but after researching his tuner is telling him he needs some kind of spacer as you cant just slap any gt500 injectors and go.

Makes me wonder if I in fact even got 47lb injectors.

So question is... how crappy (if it all) my car would run if I was tuned on 47lb injectors and maybe had bigger or smaller than what I was told..

Again the car runs fine and pulls hard... doesn't sputter or anything just a question.

Are they GT500 injectors? Or are they Ford LU47s?

Guy i bought my from was told FRPP from American Muscle. So as far as i know I have Lu47s lol no idea what hes using... my car runs fine. No issues. So all im wondering for my own sake lol is if my injectors were anything but what I am tuned for it would be running like shit.

There are the LU47 injectors that are 60mm or the gt500 47lb injectors that are 48mm long and require a spacer to bring them to the 60mm that are in the coyote.
