It has brand new injectors and new fuel filterI think the only thing left then is injectors. They can be cleaned and new orings installed. Also you mentioned fuel pressure under load, so I don't think it's it, but what about fuel filter?
They are the better style injectors and I currently have no way to data log, I ruled out vacuum leaks by spraying brake cleaner all over the intake and vacuum hosesSeems just about everything is ruled out.... I really don't like to suggest this ever, but can you possibly swap another pcm in for diagnosis?
Just making sure all things are covered, stock replacement injectors used?
Do you have any way to Data log?
How did you rule out vacuum leaks? As what method?
It can be inconclusive in EFI, to be sure you don't have a false negative, you should unplugg o2 sensors and IAC. I would also do that on a fresh reset after unhooking the battery. Can be hard to spot with IAC compensation. You might look up propane method, supposed to be a lot safer than starting fluid and doesn't ruin rubber hoses.I ruled out vacuum leaks by spraying brake cleaner all over the intake and vacuum hoses
Was it lean before the injector swap?They are the better style injectors

Was it lean before the injector swap?
They could have a different slope time than the stock ones. I'm not real familiar with the 305, but if they are a different lb per hr, that could definitely cause a lean condition.
DO NOT use brake cleaner to check for vacuum leaks.I ruled out vacuum leaks by spraying brake cleaner all over the intake and vacuum hoses
