A couple things I see in the 3rd run log:
1.) All the knock throughout the run? Maybe throw in some VP C16 for "test" purpose?
2.) The drop in o2 values at the beginning of the run? Along with the drop in spark advance at the same time? Along with the knock at the same time? But TPS, MAF, LV8, RPM, IPW, IDC are still rising or maxed out?
3.) 0.5v drop in battery voltage when w.o.t.? Battery, alternator, grounds, volt booster?
First thing I would do is get rid of the knock completely!!! I don't see the MAF or boost drop like it did in the previous logs you posted...
