Only way I know for sure is to have the dealer hook the StarScan Tool up to it, it can read the name/copyright stamp revision number and date off the PCM.
Well, you can also take a Superchips to it and try to tune it, if it's not a stock tune in the SC database, it'll come back with a "Tune Not Stock" error and refuse to tune it. I had this issue on my Grand Cherokee, before SC supported the "High Output" version of the 4.7, the HO has an upgraded factory tune and the SC read it as "not stock"...
