Cylinder 6 misfire under WOT at high RPM

I'm having cylinder 6 misfires on WOT at the very top of the rpm range. They are consistent if I do not shift in time and stay at redline. However, shifting at around 5.5-6k rpm or even letting sport shift usually means I will not get a misfire. No codes except 29D2.
Spark plugs and coils all changed (ordered just before misfire started and fitted after it started) and no change. Will pull the plug again and swap along with the coil to different cylinders but was thinking its something else?
Could anyone have a look at my log and let me know if theres anything that stands out.
Thanks
