Something is not right, maybe BPV is leaking? something is happening mid spool, that load drop is odd.

Leave requested fuel alone until you work out that load issue.

ps_w is diverging a LOT..

Has to be a BIG vac leak, between MAF and turbo inlet.

check your turbo inlets

I cant find any leaks  Undecided. Maybe N249 faulty or some check valve. I changed DV to original but no visible difference of driveability.
Maybe for tests modify file to mafless?

No, mafless is never a good idea for just about anything, least of all tracking down problems.

Is your KFKHFM stock?

Either you are losing a ton of unmetered air or your MAF is bad.

Yes, i thinking like You nyet but i dont see/hear any leaks. Maybe some pipe is air leaking when pressure is high... i dont have more time to investigate this topic... i must send car to mechanic and let him look at this... maybe he find something what is wrong. For now thank you nyet for your help... if it will change sometching in topic i will write post.
