is this the shitty wastegate on the K14 at fault?

yeah what i thought initially guys . . .but like i say, it coals at high boost, so that says to me that the fuel is getting through, it's just not getting combusted . . . . . . discuss . .

I think this is being caused by the fuel supply momentarily being interrupted as the pump catches up with demand, which in turn causes you to loose some boost. Then when fuelling is resumed you have a brief moment of lag while the turbo spools back up again, hence the coaling.

Although I may well be wrong, but that's what it feels like in my experience.

yeah i can accept that mate . . . . . . that was another thing that had crossed my mind also . . . . . . .so not much to be done then, thin it out with a bit of perv . . .hmmmmmm . . .increase internal pump pressure maybe? . . ..
