Default Kamak twinscroll turbo not boosting pass 15psi

I installed a twin scroll kamak turbo, and it won't boost past 15psi. Ran the car straight with no boost solenoid still same. There is a 20lb spring in the actuator.
No boost leaks


We tested the actuator with an air compressor and it doesn't move till 20 psi.

The wastegate flapper does have some play, but it goes seem it is sealing...

Any ideas????

Took the oem header off today, there was A small leak off the flange to the head. Resurfacing and putting it back on. I hope this solves the problem
