2G Can't turn down boost

Something is wrong, I just don't know where to start.
IR boost controller
2 Port Wastegate

So everything worked fine on my last build, the boost controller, ecmlink, wastegate ect

My wastegate pressure is 10psi, I have tested with no controller hooked up

When I hook up the IR controller it gives me all the boost. It won't let me turn it down.

I have ecmlink setup correctly, I know this because this same settings worked on my old build. Disabled error correction, enable boost control, both tables set at 0.

Where do I start? IR selenoid?
It's hooked up based on the VFAQ 2 Port diagram.

I don't necessarily see anything wrong your settings. Zero out your duty cycle table and go from there. Remember, your duty cycle table is what your car is currently setup to reference for boost. The boost target table is only used when error correction is enabled. I suspect your duty cycle is too high for what boost level you want. If zeroing out your table doesn't work then we know it's not the tune.

I figured this out, I took the waste gate apart, tightened everything put lock tight on bolts ect. And it started working, so something was wrong there
