    Throttle torque source stall

    I've got a 2020 392 with a whipple, cam, 105mm tb. I've been fighting this issue with this tune for days now. When I got WOT it closes the throttle then opens back up at about 5k rpm. I can post logs and files just wasn't sure how to add then. Throttle torque source, slow path and fast path always switch to stall. I know there must be a torque or airflow limit I'm missing.

    There is a problem with your ECT sending unit

    The system thinks the motor is still stone cold like you just started it on a 59 degree morning

    It doesn’t know it’s been warmed up

    Take it thats a hub dyno?

    No I'm on the street. It shows correct coolant temp on the log and the dash.

    And I logged the engine comment temp thru the engine and trans channels and both are at 185 or higher when I'm doing the WOT pulls
