    Take a look at the torque reduction table that's near the rev limit tables. It should show reduction vs rpm error.

    That's a lot of rpm. Are you still seeing rpm limit for torque source? What is injector DC?

    Your MAP KPA and total airflow also dip slightly right there. But VE does not.
