Warren's injectors have had their share of issues, but when they do, their customer service is very good. They (he) might be able to help you if it is the injector and you have low miles on it.
Are you sure it isn't a FICM issue or even a HPO issue? Can you post data (ICP, IPR, FICM L,V, and M voltages)?
That said, it sure sounds like an injector. You might try moving #6 to another location and see if the code follows it.
Was your HPOP really bad (ie what test did it fail)? The 05 and up pumps are pretty stout.
