Please delete all those pictures...they are too big, not needed, and it makes navigating your post difficult.

Trying updating your firmware to V8 to see if that resolves your issue.

Lower FF to 40 and do a proper log.

For proper review and the JB4 to adapt, please do logs in 3rd or 4th gear from 2K rpms to redline at wide open throttle.

ok ,i load the firmware v6 because that v8 high boost shocked me,
and that is the log, but get the high iavg
anyway ,i tried v7(switching map 5 to 4)
v8-3high boost
v6 high iavg(only one times exhaust pipe the sound of shooting when shift)
but it will be boom ever times when shift on other

kindly can i back to v5 ,its no problem for me. can you give me N20_OBDII_EWG_5.hex and let me try.

i also will try ff 40 on v8-T3later。
