Ok!
Actuator is easy to setup. You want to set it so its not so loose it vibrates and doesn't close the wastegate port. But not so much tension it'll overboost. Generally. It was to be just enough tension to hold the port shut...
Then the boost controller increases from there..
Increase the Duty Cycle 5% at a time, doing 3rd or 4th gear pulls.
Until you hit your desired boost level (or fuel cut, then back it down until it doesn't hit fuel cut at all)
Once that's done. Increase the GAIN. 5% at a time, until the boost doesn't spool any faster...
The Gain should never be higher % then the duty...
Simple Really
