Are you talking about top speed govenor or idle speed?
Also, why do you want to change the PCM?

The PCM's on some GM cars are VIN specific and must be reflashed by the dealer.

You would probably have better luck trying Hypertech, see if they can over-ride the top speed govenor with one of their power programmers.
