What car/engine? What ecu ID? Why do you want to change from 3 to 4 bar? You're not giving us anything here. In short, you will want to lower krkte when you add larger injectors, or a higher rated fpr.

golf mk4, 1.8t AUM 032HJ ECU. I change 3 to 4 bar because i dont want to change the injectors, but i want a little more boost.
I set my KRKTE from 0,1xxxx to 0,08938, but car dont working properly - afr is unstable.

Are you still using the stock turbo? Describe your boost profile as it is now. Do you have any logs? How do you know you need more fuel? What are your fuel trims with the 3 bar? What are they with the 4 bar with no changes to the tune?

Log with ME7Logger; VCDS sucks ass. Your logs don't contain enough data either. Also your fuelling is fine, you don't need a 4 bar nor is your boost profile high enough to warrant one.

Why do you think you need a 4 bar?
