You got a separate boost gauge?

First, run it with the turbo pressure reference port

(the one on the turbo outlet) directly to the actuator.

This will make it run at 0.8 bar.

You're just confirming that everything is working as it should

- it should just boost to 0.8 bar and hold.

If that's all good, plumb in the boost controller.

Refer to the instructions, but assuming it's an EBC then the usual setup is you have the solenoid sitting in between the turbo pressure reference and the actuator.

It bleeds off pressure so the actuator sees less pressure than the turbo is actually producing so the gate doesn't open.

Reset your boost controller to 0 for all values

/ set it to OFF.

0

= effectively the same as having no boost controller so it should just boost to 0.8 bar and hold.

If that's all good it's time to start tuning.

Ideally you need a nice long straight bit of

(private) road where you can do lots of 3rd/4th gear pulls to tune the controller.

Dual SBC has a limiter built in so it would be sensible to set a limit at

~16psi to protect yourself against any mistakes with the settings.

I'm not familiar with the Dual SBC, but I'm sure there are guides on setting it up out there.
