Issue seems to be cause by too high octane fuel as I added small can of octane booster + 25 liters of premium fuel.
After adding 20 L of lower octane fuel, and driving for another 100 km. The issue is almost gone, and fuel trims are looking way better now.
There is still barely noticeable blip on low revs just in 1st gear while on idle it no longer chokes.
I will empty the tank, and refill with premium fuel.
Once that is done, I plan to change all plugs as it's right time and pre-cat sensor as well.
I didn't notice at first, but in logs you can see that LFTF was over 3% which means that engine was struggling to remove excessive fuel.
So please folks, don't pay with too many octane boosters, and I think the octane value in my case was bit over 105 or 108 octanes.
