    Default DBC pcm in DBW car

    Hi all,

    Can you flash a 2000 Ls1 pcm to work on a 03 Sierra?

    Thanks,

    No, the 00 PCM is a LS1B 512kb and the 03 needs a LS1B 1MB. The tunes will not flash between the different PCMs. I believe 03-05 (perhaps 03-07) 1MB PCMs would work in an 03 with the proper OS flashed.
