    Checked Log:

    - Not too many informative channels (vcm dont support all the important channels)
    - Short Trim Bank 1 is too lean
    - Short Trim Bank 2 is not logged
    - Lambda looks good
    - Timing looks good
    - Overboosts @3700 rpm then boost drops hard which is not good

    I would be worried about knocks where it overboosts and goes too lean 25%
