    Compression change

    All things being equal, what all would you touch in a tune if you simply bumped up compression Ratio? VE and timing?

    Possible changes in commanded air fuel ratio under full throttle and ignition timing.
    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 VE tuning, or just those would be your top 2 with VE still possible?
