I have changed the fuel rail pressure sensor, upgraded the HPFP with b58 pump (not TU pump), new oem bosch spark plugs, new oem coils, i have cleaned the injectors and the rail itself. The guys who testes the injectors said that they are ok.
I am currently using a custom tune from a local tuner in my country. With the stock file the car have no issues at all.
I've imported the car from Canada to Bulgaria where i currently live. Could it be a ECU problem or i should change the fuel injectors with new one?
I really dont know what to do...
You can see on the graphic here. Red is fuel, green boost
