2-3 upshift stumble

posting in the engine forum because the trans tune is stock

i recently changed the [ECM] 44681 Spark Minimum Torque Reduction table and set much of the table to 7 deg, previously it had values from -39 to 7. after this change i often get a stumble during the 2-3 upshift. i attached a log file (and tune), at the 8:11:52 mark you can see an example.

maybe my change to the table was too much, and i need to put back some of the spark reduction?
is there a method to address this another way?

vehicle is a stock durango rt 5.7 8HP70, only mod is SOS coils and the larger plug gap

I'd suspect the stumble is related to an ignition misfire as indicated by a massive lean spike shown on the log as the large shift in Short term fuel trims of about 20%. STFT jump from slightly too rich about -5% all the way to +16%, but only for a brief instant.

Log Misfire counts to verify.

Knowing that you touched the plugs and coils is verification that it is probably a misfire.

dave ^^^ is a smart guy

that very well might be why it stumbles at that shift

but why 2-3?

why only 2-3?

i have a theory that there is a glitch in the system

it does not present itself in all cars but i have seen this a few times and that is where it manifests: 2-3 shift

i do not understand how it can be in some cars and not others?

i have had to tune it out in the transmission tune on a few cars

i reset adaptives incl fuel trims after i made the change so maybe that lean spike is temporary as the trims systems does its thing over a few drive cycles?

i've been tinkering with this car and its tune for a couple years and i've always had this issue at 2-3 after changing this particular 44681 Spark Minimum Torque Reduction table. only now i decided to message the forum. sort of nice to see someone else witness a similar thing.

out of curiosity i updated that same table changing the 7 deg cells to 0 (and reset adaptives again) and so far i am not experiencing that 2-3 shift stumble. and i did log for misfires and there were some, mainly at startup. no engine light on dash so i guess not enough misfires to worry? anywhere from 1 to 6 misfires. logs attached.
