You are correct, however whatever injectors GM used are notorious for just pouring fuel out of worn tips. My test would identify horribly bad injectors. If if can't hold fuel in it with the car off its bad. It will not reveal the poor patterns but if you're running pig rich and pissing away fuel that can sometimes find it.
