Its showing 9.2 inHg MAP, which means your ETC vaccum is more like 28.3-9.2= 19.1 inHg. The table resolution doesnt do very well representing that much of a difference, so it depends a lot on the torque model to make the feed back loop accurate. People have a hard time dialing in the larger throttle bodies at idle as it isn't so much about the TB model and more about the torque model and getting your DD torque lined up with what your torque/load inverse tables are saying. The 11-14s had some airflow tables for idle and basically used torque for return to idle, so they were a little easier, but you would still get rev hang and stalling issues is torque wasnt fixed. The 15+ use torque nearly exclusively at low load.
