Quick update : I haven't noticed any problem so far (boost dip) / torque limitations
I've re-uploaded the latest firmware version for the JB4 (60/5//5)
I've also disabled the direct acceleration tweak via VCDS. I've put it back to : "incremental controlled over time"
Trying to abuse the car a little less so I haven't done any WOT with the JB4 logging. This is based on 1 or 2 WOT without logging.
