    On my iPad, so can’t see your tune, but I’ve noticed that increasing some of the stock torque limits in the tune can cause this issue. There is a stock torque limit of 369 somewhere, try with that unchanged.

    This is the main issue for your targeted stoich.

    Your MAF vs PERIOD needs to be rescaled back to stock. Then the higher flow rates need to be rescaled again. I rescaled by removing 4 axis values to add in 4 more axis values between 105 and 83.33. Even then, this is how mine compares to yours.

    lb/min Airflow
    55 - 229.5
    65 - 212.59
    75 - 172.73
    83.3 - 137.4
    105.4 - 92.5

    lb/min Airflow
    83.3 - 91.54
    88 - 83.68
    92 - 76.99
    97 - 68.63
    105.40 - 54.58

    Make use of the cells you have available. There are a lot of adjustments you can make to get it running better. Id get rid of over half of those mapped points to make the quantity of mapped points adjustments through out the tune more simple. Why adjust 25 tables in four different parts of the tune over and over. That's 100 tables to adjust. You can narrow it down to around 10 tables in four sections and cut your time in half and it's just better, much easier and you can get it running the exact same way.
