Please post logs showing large positive deviation (which is UNDER boost, btw) BEFORE the car goes limp. If you are seeing 10% WGDC, it is already limp and the log won't tell you jack.
I'm guessing boost leak or DV failure.
Or possibly insufficient I-Max at redline (on the one good log, I see there is some deviation at redline, and pre-lin meets the ilimit)
I don't see how this has anything to do with a bad MAF btw.
Here is a log before the car goes limp
