your MAF is either really bad or something has really really screwed up somewhere, its reporting something like 280 gm/sec - it should be 2.8 gm/sec at idle and the injectors should be at about 2 ms at idle

try running it without the MAF and see what happens, I had this issue in another car (Chevy 3800) - the MAF was reporting more air than the engine could actually consume at WOT at redline, same issue as yours, fixed by a new genuine Hitachi MAF.
