is that even allowed for anyone calling himself an engineer?

How does the simulation handle the throttle and airflow into the engine?
With a 'normal' plenum intake, you could add a 'quick fill' throttle target adder which sets the throttle over-open or over-closed to reach target MAP more quickly, but that shouldn't be a problem with ITBs.
It a power generated minus power used. The power used is friction and pumping losses which are based on the BMEP formula... times 2 because it didn't seen enough...so it's a bit of a guess. The flow is based on TPS and available flow area, and some tables to convert to MAF and then MAF to MAP...which feeds the pumping losses.
Right now the throttle stay open until it hits the limit (as you want on a performance setup) but then simply can't react quickly enough to close it so it hits the hard stop and bounces the throttle closed in 4-6 bounces. I may do something to prime the PID so when it hit the soft limit it slams the throttle shut. It works with a less violent input, but WOT in neutral with a powerful engine....it bounce a bit playing catch up.
