Hello awesome board working on my first tune for an MKIV GTI,

In order to get the boost up to 20lbs I have had to raise the max filling and target filling tables much higher than I would have initially thought, they are in the neighborhood of 300% is this normal?  -or am I overcompensating for something else?  The boost profile is fine but having to scale up target filling so much seems to make for a jerky/unreliable pedal.

The boost related maps changed so far are Target filling, Max filling, Max compressor pressure ratio, and optimum engine torque.  Thanks

Meets the requested boost, but in order to get the requested boost up where I want it, I feel like I've raised the max filling and target filling too high.  In your tunes to get 20lbs of boost do you end up having to raise from 170 some % filling all the  way up to 300%?

I am getting quick spool and N75 duty cycles up to 100%, which makes me think its not a PID issue though.

optimum engine torque is wrong.  all you need to change is pressure ratio map, LDRXN, and requested load.  This will get you your boost.  Tune PID if it isn't getting there as quickly as it should
