When you changed the boost control piping from the turbo outlet via the t-piece to the actuator did you take the brass restrictor pill out of the old pipe and put it in the new one. Without the restrictor the turbo boost pressure will act directly on the actuator which is set to begin opening the wastegate at 6-7psi (about 0.5bar) and therefore you will only ever get 0.5 bar of boost.
