    Lean when revving/burnout

    Took the car to the track the other day to take a look at the tune and It was showing it was WAY lean during the burnout and when revving up at the line. The AFR is pretty steady around 11.8 during the pass as soon as I take off the AFR goes from that way lean to the 11.8. It's an ls1 PCM from an 02 Camaro. It seems to me like I'm missing a table that should have been tuned would appreciate any input. Thanks

    Post the tune and any log you have.

    Can't tell you much without seeing what's going on.
    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.

    I fixed the throttle hang since this log. I also made a fuel adjustment in the upper RPM where it went unsafe lean.
