Not necessarily. You can have an injector that works fine under load but not at idle, or one that fails under high actuation pressure.
Without cat et you really are just guessing
A much better use of money would be new injector o rings, new injector hold down bolts and maybe even new injector cups if you were up for a challenge. These are known failure points and are relatively inexpensive, in the grand scheme of things
