I'd check to see if the boost is standard. Make sure there isn't a manual bleed valve or something under the bonnet.

Could well be a major boost leak lad, the standard intercoolers on them are shit. take a look around the flanges on it for cracks or holes. It sounds like massive overfueling cos the afm reads a certain amount of air going through it an fuels for that amount, but your loosing alot of air somewhere in the pipework which causes all the missfire and crappy performance;)
