    Your MAX torque timing tables goes to 30, I could see it maybe going there for a number.

    But you are out of fuel big time, you hit over 112% duty cycle man. You ran out of injector ages ago.
    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.

    Yes i see that, but if you can make the air fuel go into the low 11s on a NA car your not out of inj yet

    why would it be doing that, not normal operation for a gen3 pcm
