    Default 1999 Silverado pcm

    99 Silverado w/5.3.Is there a COS for OS 09379910? I have an extra 99-02 pcm from my C5 vette with a COS#5 OS-02020005 Could I use that pcm and would I have to swap all the cal.info over? Or is there an easier way............................Paul

    Start with a 5.3 truck file with the operating system 12212156 from a 2002 vehicle. That would be the best way to start. You will first need to transfer all of your current tables to the base file from your 1999 tune, its tedious but not too bad with two EFI_Live windows open at the same time.

    Use copy-with-labels and paste-with-labels... this aligns the pasted data into the right rows/cols.
