    Drag car tuned by local shop but having Burst Knock issues

    I am new to HP tuner and doing a lot of reading / learning. I am having Brust Knock issues when leaving the line or when I am coming up on the two step. I was hoping you could look at my tune file and log files of some runs this weekend and tell me what you think.
    Thanks

    The problem is that the burst Knock will show up on one run and other times it wont. since this is a Drag car its make my car very inconsistent. My guy that does my tuning is great but I am trying to learn myself as i find it very interesting.

    its directly related to ecm predicted air flow changes and throttle changes. you can remove it if needed.
