1) Yes.
2) Yes. But if duty cycle too low desired boost may not be reached so up duty cycle and try again, try not to overshoot(duty cycle) too much (might break turbos etc) also if duty cyle too high can produce surging and extra lag
3) No. Once duty cycle changed desired boost level must be reset (driven up to)
4) Yes. But meant to be done after step 5
5) Yes. The closer to maximum gain, the more unstable the boost can be. Min(0) Gain, stable boost but minimum respose. Max Gain, solenoid begins opening at 11 psi (for 12 psi setting) therefore quicker boost response but may suffer from boost instability.
For my GTR Gain set at approx 2 psi below desired boost level for good response and stability
N.B Duty Cycle can only be between 10% - 90%
Yes i set duty cycle and drove to desired boost Computer will NOT decide duty cycle for you
Hope that answers your questions if not ask more
