Has the PCM ever been replaced?

 

I had a customer with a similar issue. He had a 5.3 truck and I found the computer had been replaced with that from a truck with a 6.0 vin. Reflashed the PCM Codes went away.

My programer states its flashed to a 5.3 so I doubt thats the issue, could double check! will the difference in brands acctually make a large difference?

also I'm thinking possibly clogged cats?
