OBD1 PCM interchange/compatibility, 5.2 vs 5.9

I haven't tried running the motor with the '92 5.2 PCM yet, but I will soon, at least so I know that much. I'm not using the 5.2 injectors, but ones that are supposed to flow a bit better from what I've read. My fuel pressure's in the low 40s according to my gauge, but I was going to try it on my '95 5.9 truck to see how accurate it is. I also have an Innovate A/F gauge that I may tap in near the O2 sender, just to see where I am. Not sure what I'll be able do with that info though...
