I reset the ecu per his request and re ran the logs. This is his response:

“the tune is perfect now. The sluggishness you were feeling is due to the long term fuel trims degrading the original tune. It seems as the long term trims were taking fuel away from the tune which caused it to lean out the full throttle portion.

Is your PCV deleted currently or are you running the stock PCV setup?“

I told him I’m running dual catch cans, he advised:

“remove the catch cans and run a proper PCV delete so we can track how the long term trims are moving”

So, we’ll see what happens I guess

Who's your tuner? I'm curious to learn the reason for tracking the long term trim with a PCV delete vs keeping the PCV and catch can.
