Default 2004 ECU in a 2003 car?

Since the 2003 had different programming. Can you put the stock 2004 ECU in a 2003 after you program the correct VIN in? Can you put a Stage 1 for a 2004 in a 2003?
I have a 2003 Dream Series 2, automatic. Runs great, would like a little more UMPH without getting crazy.

I bought and installed a stage 1 for an 03 in my 04 turbo lite. Gives the umph you are talking about but I have an issue with the a/c only working with a jumper wire.
I just found an 04 stage 1 and ordered it. Will have it installed and flashed to my Vin next week. After that I will offer my 03 stage 1 for sale.
