Wastegate actuator signal line should not be plugged into intake manifold. Wastegate actuator is NOT designed for vacuum. You may have blown out your actuator which might account for why you aren't seeing boost like you should.

EDIT: with a properly set up EBC you might be able to deal with it, but if you ever run straight wastegate (for example during warm up) your actuator is seeing vacuum.

Ok got that thanks, I'm wondering now if I've got the answer I just gave for the wastgate signal line wrong. I will have to check tomorrow. I've got it in my head there may be a brass fitting on the turbo outlet it's connected to !! Does that sound likely ?
Now I've just googled it though that sounds like it's not ideal as it should be after the IC but before the TB.

Likely.

Not ideal, but not harmful. Anywhere before throttle body is safe. Anywhere between IC and throttle body is ideal.

If you're using electronic boost control you can connect from anywhere between the compressor outlet and the throttle body. The location near the throttle body is only critical for manual boost controllers or no boost controller.

Ah that's good news because I am using an EBC and it is getting the line in from the turbo outlet.
Thanks guys, now just need to tweet the boost duty figures.
