If the prom from the dealership had the same BCC as the prom taken out
of your car, there were no changes between the two.  If the ECM is
original, and the 4 letter code on the label matches your prom, then
you are running an original release prom.  Any later fixes will come
with a prom of a different BCC.
HTH.
