Focus MK4 ST Ecoblue problem

Hello, I have problem with my car it's Focus MK4 ST Ecoblue 190hp 2021 with 112000km. When engine is cold car acts like it have half of power, when is hot in 95% time goes like it have 140hp, and rest of 5% goes like hell😔. When I connect Forscan doesn't have any trouble, MIL doesnt turn on like there is no any problem but car wont go like it should. I monitor turbo pressure on my dash. In most case wont go higher then 1.4-1.5bar. When he is good well in little time goes to 1.7-1.8 bar but that is in 2800-3200rpm after that start dropping pressure 1.6-1.5...on 3600rpm I have only 1.3bar. Does anyone have some advice where to start looking problem and does anyone have here that engine that I compare turbo pressure. I was replace plastic pipe from turbo to high pressure egr becasue it looks on side of turbo flange have little leak but it's almost same. Car have watercooler and there is little possible places to loose boost pressure (not like it have intercooler and 3m of rubber pipes and many places where it can leak). It's strange that doesnt have any fault (underboost, dpf, catlyc, egr... )
