If you installed it in line with the bcs then you won't be able to use the mbc unless you change some tables to keep the bcs closed.
I tuned the car, no ebc used and the wastegate/MBC have there own dedicated lines. The boost reference I'm using is coming from just after the turbo (can only see boost, no vacuum). Is this correct?

It's an internal wastegate. So my only solution would be to change up the wastegate actuator with one that can hold 22psi from ATP.
