OK...just ran a search and I believe your fuel pressure is rated at 58psi...same as my 98 5.7L L31 right?
If so...and you're running 42lb injectors...I believe your IFR tables (B4001) are wrong.
I believe they should be set to 6.109375 instead of the 5.296875 you have in there.

Merry X-mass. This should help it idle better and run smoother.

Edit- I didn't look at your logs.This is just hitting your idle and timing transitions.
