Blanked of the icv and vac pipe to the diaphragm valve, that combined with the lambda sensor it does seem to be running smoother and picking up better, but its still not running right at full boost.
Seems to only happen at full throttle, full boost, after 3.5krpm. Im convinced theres a boost leak somewhere. The recirc noise from the turbo changed dramatically shortly after i started having the problem too, originally it was one smooth "hiss" but now its very prominent "flutter", which im led to believe may be a fault with the recirc valve, so blanking that off is going to be the next test i think.
