    Assuming no boost leak, i'd go for the MAF sensor. Disconnect it and take it for a drive and see if it's ok now

    Air leak. Check all the pipes and hoses around the inlet manifold, and then do a pressure test if you cant find anything.

    Try the fuel pressure regulator pipe at the back of the inlet manifold near the bulkhead and also the vac line to the DV there prone to distort and leak.

    Have you checked the dv as when I took mine off to replace it with a forge item the diaphragm had a split in it and you could blow straight through it with little effort.
