Most likely the reason it is pulling timing is because you are hitting TQ limiter on gearbox.
Also, hook up a wideband and verify the AFR you think you are running is what it is actually running.

Gearbox TQ limit will not show on CEL when i hit them? Only silent fight with engine ecu?

And another question, why ecu request more boost/load after gear change(example 3 to 4)? Some correction?

It most likely does not request more load, but requests more boost, because the IAT is up.
Basics!

Yes, no CEL, it's like ESP.

try going WOT in 5th gear at about 3000 RPM and then report back

I have no logs because I have a boost gauge (makes things easier)
