Anyone know where Turbo Airflow Desired is calculated from? My desired turbo airflow may be around 30lbs min while my actual turbo airflow is around 38lbs min. May or may not be an issue, but I still want it to match up a little better.

Good question. Got a focus ST in the shop right now for dyno tuning and turbo airflow desired stays stock regardless of what I input in the calibration. Phoned a friend and neither he nor I have any idea how to "turn the boost up" in this 2018 Focus ST 2.0T
What does VCM Scanner say is limiting the airflow?Quote:

It would jump to the multiple hundreds of desired airflow, with actual going as high as it could, within the other limiters present.
