I was just wondering if there's any way to tell upgraded injectors from stock? just curios becasue with the mods done to my truck it seems like it has more boost than it should. the mods are an Edge EZ chip K&N cold air kit and a 5" exhaust no cat or muffler. it will peak at around 33-34 psi. I've seen other Dodges same year with the same mods but they have Edge pro comp chips and they only hit 25 psi.

 

most of the time the only way to tell modded injectors from stockers is you have to pull them, but I do know of some that have the stock Cummins part number.
