Boost controllers don't set "boost" in PSI. You are setting how active on a time scale (or duty cycle) a solenoid is that bleeds air. The amount of time spent bleeding off air then dictates how much boost pressure the turbocharger is able to create.

Do you have an Apexi or HKS boost controllers? HKS has a model "EVC" where Apexi does not.

Lower the duty cycle and try again.

I have an HKS EVC-S and it does the same thing. Super frustrated trying to figure it out ever since I installed it. Even adding an FCD didn’t solve the issue!
