MAF booster is already on my table But the weather is too bad to mount it in the car

Lithuania

Ok, I'll try to do this in the nearest future Now it is heavily snowing, so it's a bit dangerous to do those tests on the roads

But if we look only at the boost pressure signal, is it correct? Because I didn't noticed any problems with turbo boost, it starts to boost at about 1800rpm and I think if I'll change my MAF to the new one, my car would run as it should with 74kW

I don't understand only one thing, why those two signals (boost pressure command and boost pressure) are not connected? I think when the boost pressure exceeds predefined value (1.85bar) ECU should open the wastegate and lower the boost presure, isn't it?

Hi,
Sorry that I write in english, hope you can understand.
I've found that there is a lot of smart people here, hope you can help me 8)
I have the following problems:
1. There is a difference between the desired and actual timing on idle speed, why?
2. Boost pressure command doesn't change, why?
