    Can't you just copy over the stock VVE into the 2 bar OS and have your stock starting point.

    Of course you'd have to use an excel program to swap the numbers around to make it work with the 2 bar OS axis's.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    You should be able to use the stock one and use Excel to transpose it and flip the axis around to make it work for the new OS

    Stock VE (IMRC open and closed) tables were empty, and i could not find VVE table.
