Perhaps try make contact with Rudi Dudi ...I believe he makes a wonderful lemon drizzle 😂

Update: it does not feel OK.
Today, I tried another car with 600k km on the clock (200k more than on mine) and it was way faster than mine. So I checked the injection quantity on both cars. The faster one says 2.7-3.0mg/stroke, mine is steady 4mg/stroke at idle and changes when I push te acc pedal. After that I went for a spin with Vida connected to my car and the desired boost pressure is always 0.3-0.6bar above the actual pressure. The bigger difference is in the lower rev range, the smaller difference is in the higher rev range and the actual never reaches the desired value.
So took the metal pipe off the wastegate which comes from the compressor housing guessing it should have full boost and should go into limp mode if it reaches too high boost pressure. Well, none of that happened, the car felt the same slow. Does that mean the wastegate is stuck open?

Will definitely do - if only for the chance of drizzle on our way back! Thanks.
