I think the VGT parts are coked up. I had that problem on a 2003 so bad that Ford put a new turbo on it. It couldn't get out of it's own way. Once the engine warmed up it starts to free up a bit.
There is a procedure for removing the turbo, breaking it apart, cleaning, and reinstalling it. It works wonders. Unless the turbo is too cooked to get clean. I just got done doing a turbo for a 2004 E450. It was pretty messed up, far worse than what Ford would just throw away. I cleaned it anyway, and it seems to be working pretty darned good.
