Technical Bravo 2.0 Wastegate pressure

[nigel3a]

Been having a few issues with mine, I may have narrowed it down to possibly the wastegate actuator. There are too many different versions out there, with varying psi pressures. I've seen one which will fit, the pressure range is 18 - 30 psi. How can I find what min / max psi mine should be.
It's an 09 Bravo 2.0 165 bhp
