I've seen that the PCM's for LS1's are sam across the board(Pont, chev, etc.) for whatever year. Is this also true for '04? Specifically the GTO?

I'm not 100% sure so hopefully someone else can jump in... I know the GTOs are 1 MB flash memory (compared to the 98-02 F-Body LS1s that were 512KB) ...

but not sure if the 04 LSx based motors use the same pcm as previous years tended...
