    Torque Model?? Lower "Actual Torque" vs Airflow than expected

    2016 Charger 5.7, 2650 Blower; 8HP
    Max Pressure Ratio ~1.7

    The car came with an Engine tune from the blower manufacture. Its attached

    I was trying to improve shift performance but when logging I noticed the Actual Torque lower than I expected.
    I fully was expecting the PD blower would cause the Torque Model to be hitting limits and causing issues but not so.
    Max Torque observed on the log is typically less than 500Nm.

    I also didn't see any significant changes to the Torque Model or Airflow compared to a stock tune.

    Since most of the TCM tables max around 700Nm, my goal is have the PCM report Torque in the ~650Nm range.


    Should I just say "F it" and rescale the TCM to max at ~600Nm or Fiddle with the Tb Airflow and/or Torque Model to get the Torque up a bit?


    Whats the best practice?
