I am worried coz after 6000rpm ps_w not follow pvdks_w. It's not slighty below like it should be and I dont know if i screwed sth with MAF calibration.
ignore that until you fix your other problems. One thing at a time. At your completely fucked boost levels it is literally pointless to worry about ps_w as it isn't even close to being in the operating range that you want anyway.
You're literally worrying about the wrong thing.
Always start with the things you know are broken. Ignore everything else. Fix them, one at a time, DTCs are a priority. Don't be cheap. Don't be lazy. Don't work around them with some halfassed bullshit or an excuse. If you can't figure out how to fix those, or can't afford to, or are too lazy to, ditch the car.
