Did you check for non-tune related misfire problems?
Also that log format is not standard.

Hi
It is log from maestro. Yes I check every thing not tune related. Check plug gaps is 0.026 and COB connectors.
Can over fuelling relate to this problem?

If ME7L supports your ECU please use that format.

Mine was doing the same thing at 4000 rpm changed plugs, coils and fixed coil plug wiring and problem was solved. The wires going to the coil connectors deteriorate over time. Check all of those.

9 times out of 10 misfires are from hw issues, unless you really fucked up your tune badly. |

BKR7E/IX work well for most people in tuned cars.

No point. Just start swapping them and see if the misfires follow. |

Installed new BKR7EIX plugs and misfire was gone. As i was doing more wot test and the coils getting hotter misfire returned on 4000rpm.
At least it was not so heavy misfire as before so i suspect a coil is on it way out. Will do a test early tomorrow morning in colder whether.
