When I sit there and rev up, I get a rattle coming from the turbo area when the revs come back down again? It's definitely from that area.

Also occasionally when I put my foot down (change down and floor it), occasionally it theres a hesitation as if the turbo doesn't come in, and then all of a sudden it's on full boost and fine? Any ideas, could they be related?

The second problem is it mapped by any chance as its well documented if it is,

Mine does it but it seems to do it less with traction control turned off

Nope it's standard, no map.

rattle - maybe a heat shield (a bit further back though), or bolt loose on the manifold?

Heat shield did cross my mind as it sounds something like that.
