Your tune can't affect your IATs...if they are high, they are high....

excessive IAT may lead to some KR, should be able to scan it to see where the issue is.

How hot is it there? Bank one shows 50mV in the middle of your pull. I see hot coolant, hot air, and a potentially lean mixture. Do you think that's really how hot the intake air is?

I don't have HPT on this PC, but what's your knock issue doing? If it jumps right to 4 degree's of knock and stays there, you may have bad knock sensors. I've seen it a number of times on 97-98 LS1's.
