probably yes
either they have a "slave" Master tuner software in a backup-workstation which they use offline to mod usdm tunes

or they saved a lot of pre-modified tunes while they still could (you can t really not update a main master software as you need it to connect with the license servers and stuff

For example in your case Ryan they d only disable the P0420 for the CEL of the cat and everything else is enabled
NA tunes made from Zach for restyling cars are like 80% stock in many ways
Not complaining of that, they re smooth and OEM feeling which is nice

It should have, like stock tunes from 2018> , a change of "personality" when the ECU seea the value "exhaust catalyst temperature " of over 870 Celsius
which can randomly reach depending on which aftermarket header you install (some have the bungs closer to the exhaust valves) but shouldn t happen a lot with your config
when you go over 870C target afr changes a lot and some of the closed loop that he kept active untill 6400 rpm in your "base" tune will turn of and from what i remember from your logs, it will become a bit too rich when the threshold is reached
which then will cut down the exhaust temp and go back to full performance
