Hi all,
So after much head scratching and Vida deciphering, I came up with a plan, the boost control valve has always made a bit of a weird sound when you turn the engine off and Vida was saying the wastegate was at 100% most of the time, so I figured I'd start by there and bought a good used bcv.
Went out to swap it over tonight and what should I find?
One of the vac lines has had the factory clamp replaced with a cable tie, when I removed the old valve lo and behold, I found the culprit, the local garage who I trust for "small jobs" has snapped one of the outlets and glued it back on!

Replaced it with the new one and took it for a spin....sorted, back to pulling like a train.

Moral of the story,
Don't use a crap mechanic
And if you hear hooves don't go looking for zebras, it's probably just a pony.
Cheers for the replies, if nothing else I've learnt a lot about turbos.
