I would be looking for a leak in the intake past the maf. If you are running the stock cloth maf to turbo pipe I would bet a hole has formed. I have used electrical tape in the past but a metal pipe or new cloth pipe might be in order.
Next you might put a gauge on it to verify fuel pressure. It is spring, probably time for a new fuel filter anyway.
