the table isn't very clear ian,,,
the maf seems to overread sometimes for a bit too long,,, and that's VERY strange, not? if it was shot it should underread,,,
Sometimes I get something that sounds similat to your problem by what you wrote,,, supposing it is the same thing I'd eliminate the turbo since mine is VNT and yours is wastegate,,,
will try and swap the maf and see what happens,,, you can try that too if you got a spare maf,,,
