new turbo needed, anyone had the darkside devolpment turbo package

[rench]

Just had clutch and single mass flywheel done on my 2.0 gt and now that turbos smoking badly and no power, been going into limp mode a few times before hand aswell. so ive been looking at this kit

thought seen as id be spending £900-1000 on a standard turbo i mayaswell pay extra 500-600 and get the 200bhp kit or 220bhp. anyone had this or think its a good idea?
