Uneven LTFT - Lots Of Misfires - 2019 Chrysler 300M w/ 5.7 - tune & log attached

[AC3]

Hello,
Customer brings me a 2019 300 M with the 5.7 HEMI. Car has long tube headers. K&N cold air intake. Stock otherwise. I have attached a log file and the stock tune (this is the first read-back after getting it unlocked from HPT).

The LTFT are +30 on bank 2 and +16 on bank 1.

Lots of misfires on bank 2.

Car has new plugs. No apparent exhaust or vacuum leaks. The problem seems to be isolated to bank 2 and I have checked the obvious things. Has anyone seen this? Any advice is appreciated.
