Outer Limits 4x4 Board

For those turbo guru's in the the know, I have an actuator with the code
AC-13 52A fitted up to a turbo I just bought second hand (thanks Daniel)

It from a standard 4.2 GU turbo setup, but I am unsure if it is standard or not.
Its not fitted up yet, didnt want to run too much boost so need to know if I should get something different before fitting it up.

Anyone know what boost this might start opening at ?? 13lb ??

Put some air pressure on it and see what it starts to move at, and pressure at full travel

Bike pump and pressure guage is the most controllable way to check it.

Ahh now that makes sense, I was wondering how to check it, I will go try that now. Cheers.
Also I think the wastegate is a factory GU one, just looked huge.
