Possibilities:

Injector scaler too high
MAF scaling too low
Fuel pump can't keep up
Clogged fuel filter
Failing injector(s)
Massive vacuum leak
Failing MAF sensor

As others have said, the appropriate things need to be logged. Do not do anymore WOT without logging the right stuff. Log, log, log!

It could be knocking like crazy because of the lean condition. I had a very similar issue a few years ago and it turned out to be a fairly large vacuum leak and a faulty MAF sensor.
