ECU pulling lots of timing in cylinder 5

Hey,
I've tried multiple tunes on this car (cobb OTS Stage 2 93, Cobb OTS E30 and my own custom E30 tune starting with Cobb's OTS E30 as a base) and they all result in the same issue. Lots of timing pulls in cylinder 5. Every other cylinder usually has very minor or 0 corrections.

Car has BMS DCI and Chargepipe, Mech Tuning 5" IC, VRSF catless DP and a custom catback.

I already swapped injectors, ignition coils and spark plugs with cylinder 1 which never had any corrections and it still stayed in cylinder 5.

Logs attached.
Any help is much appreciated.
