Carb on idle is fine, slow driving also. No overfueling at in vacuum at all but when car is under pressure everything over 0.2 bars it starts massively to overfuel and spit petrol on overfuel valve. Cup mode is done. I blanked in-car boost and DV. Any ideas?
Just to add. It seams that fuel is going out instead in inlet manifold since engine temp. is rising while car is under boost.
