    Changed it from what?

    Different years used differnet firing orders, pretty common to see on the early LS motors. Many of the LS trucks from 99-00 have different firing orders than 01+ motors.
    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.

    No they don't. The firing orders are the same just the number it starts with in the calibration is different. Makes no difference.

    That is what I mean, the order on in the table never changes just the number it starts with. Maybe my wording isn't 100% spot on but that doesn't mean I'm wrong when you look at the table.
