    I see, your 2000 is not listed...

    then do this:
    - compare your 2000 file with the 2002 Trans Am M6 12212156 file, and copy all tables that are different (it's a little tedious, take your time and get it right),
    - full flash the edited 12212156 file and make sure your vehicle runs at least as good as previous;
    - now you can upgrade to 02020003 or 03030005.

    The Corvette is Drive By Wire (DBW) and the trans am is Drive By Cable (DBC) so you couldn't simply
    flash in the file, you could however look at the fuel and spark tables.

    There are several versions of 12212156 out there. A good example would be the guys doing the 12200411 PCM swaps into GMT400
    trucks had a difficult time getting the push button 4-Lo working, some S-10 calibration segments were used to overcome this issue.
