    09 Challenger Stuck WOT

    Need a little help, tried a few changes with no difference. Procharger D head low boost (5.5psi) throttle hangs after 5.5k.

    Need to log calculated MAP, throttle flow, idle torque, throttle adaptives, torque adaptives, phi adaptives...anything airflow related that you can find.

    Maybe it has to do with your throttle body airflow model.....and feedforward.

    try to scale it ...seems a little to narrow in high position...

    I am no pro but looks like your large range (yellow curve) deviates from your main airtable.

    From info in these threads you want to keep all three tables essentially identical.
