There's some stupid settings in there. Why would you want max torque set to 350 on an 8.1L? Below is what I see for 2001 and 2003. The rest of your numbers are close/same.
Throttle control is only one of the means to limit torque. They also cut spark and can turn off injectors. There are torque management settings just for the transmission that haven't even been shown here yet. They can cut torque up to 55% during a WOT shift. Then there's the regular torque limits we've been discussing here and notice that only ETC Limits have to do with throttle reduction. Therefore, those numbers might not matter here? It can also cut timing as part of traction control, but throttle is the primary device for that (well, and ABS..)
Yes, with misfires, you can get rich mixtures coming out, but the O2 should still read lean, regardless of why it's misfiring.
Run through the ground check stuff we talked about the other day, make sure you dont engineer a ground loop in there.
I was thinking the sensor could be fouled like the plugs. I read about people using an extension on the O2 sensor to help keep it from getting fouled so I put one in the crew cab some time ago. But maybe that could be why the new PCM is better but not right.
So I don't know the condition of your engine or your exhaust system but is there a possibility that it is the engine?
why are there negative numbers on the kPA here?
Someone please correct me if I am misunderstanding, but don't we want the abuse mode off?
This suggests that the MAP sensor is working, and the timing is being told to be cut, but not on BKR or KR
