Yeah the 4.0 guys are the ones this matters for. The 2.5ers use I believe 17 lb injectors at 39 psi, so virtually any option including the ones rated at 19 @ 49 psi should be fine.
I suppose you could end up too rich if the injectors flowed way too much and the computer couldn’t shut them off quickly enough, but I don’t think that’s much of a concern.
