I've been testing out a theory that I have a leak somewhere, going to do a proper test later and pressurize from turbo to throttlebody

Yesterday I ran with the BCS solenoid unplugged and I was expecting to run at around actuator pressure, currently got a 13psi static break. So I'd have thought I'd see around 13psi worth of boost?

 

I'm actually seeing basically no boost in 3rd gear and then I get a little bit in 4th when running at actuator pressure, is this normal? I would expect with turbo connected straight to actuator that I get whatever the pressure of the actuator is....?

That is not normal.

 

Connect a vacuum pipe from your inlet manifold directly to the nipple on your actuator (ie eliminating the BCS). You should then see a maximum of 13 psi of boost in any gear. This is a good basic operational test. With a max of 13 PSI your power delivery should feel pretty smooth.

I suspected as much. I will try straight from inlet to actuator as suggested.
