Get the wastegate closed off to eliminate it as a possible leak, then, if that is no better you almost certainly have a split or hole in a boost hose or pipe.
If it is better, get a better actuator or leave it closed, up to you.
Could be shagged turbo but if you can feel a TD04 spin by hand then it'll be 'reet generally.
Also look at how it is mounted to the manifold as any leaks there will kill any boost occurring.
