OBD1 PCM interchange/compatibility, 5.2 vs 5.9

I did not read all the above so forgive me if this has already been covered. My 95 Dakota has been running on a Mopar Performance 5.2 module for 16 years on a mild 5.9. It runs great for what it is and gets good fuel mileage. I do have a 5 speed though so I cannot help with the trans. questions. I run my 5.9 on 24lb injectors and yes the 40psi fuel pressure is correct. I believe the return system was threw 93.
