OBD1 PCM interchange/compatibility, 5.2 vs 5.9

Hopefully i'll get a chance to test my fuel pressure today, planning on bypassing the relay and running the pump with the engine off. I fgure that will show max pressure from the pump. I read that the MP PCMs do well adjusting to/learning fuel curves, but again, this is just one of many things I've "read". The 24# injectors you're running, are they factory pieces? Grey or black tops, perhaps? And thanks for sharing how it's worked for you.
