Help with misfire

I keep getting cel 29CD (DME: Combustion misfires, cylinder 1) only when I go over 6000 rpm.

My car is 2014 E89 Z4 with FBO. I have new ngk spark plugs gapped to .022 and new coils. I am running mhd stage 2+ 93oct.

I have tried the following to isolate the problem:
Swapped coil in cylinder 1 with cylinder 2 same issue.
Swapped spark plug in cylinder 1 with cylinder 2 same issue.
Swapped injector in cylinder 1 with cylinder 2 same issue
Removed and cleaned vanos same issue.

Any ideas or what could be causing this? Car runs perfect until WOT over 6000 rpm and cel comes on dash. Clear code and no issues. I am clueless at this point. Attached is my most recent log as well. Any advice would be appreciated. Let me know if any other information is needed. I am new to this and might have missed something.
