Sorry for my non-tech writing, and yes we changed the vnt on the side of the engine mounted on the engine block above the starter motor.

We have tried another turbo but the results ware the same. We have also taken the turbo on a machine to be checked and set right. the told us the turbo is OK. Turbo removed, EGR removed and intercooler removed and checked if it's OK

One point in time we have managed to fix the performance a bit, but went back after we removed the intercooler and tried another turbo.

Here are two videos with the parameters you asked, but on graphic display we can choose only 5(max) out of 8, after that we stoped and second part of the recording is with values of all parameters.

This is video on ringroad around the city:

This second video is on a uphill, when i press on the RPM sensor around 1min we are in 5th gear with pedal all the way down. the car is just on 2k rpm and on 1:20 we are releasing and pressing the pedal so VNT is jumping a bit. On 1:40 the hill is over when i press on VNT sensor and RPMs are jumping ...

Also i should tell you the car was driving for 2 hours and i can't get the kick and stop just slow smooth week performance.
