well i put it back to 11 - 11.8 when im on throttle but still the problem if im at 2000 rpm at 4 gear and low speed and push the gaz pedale full down its lean like 18 on afr and than slowly goes to 14 .13.12.. on boost

and also if i direct push the gaz pedal down i have some misfire at high rpm

i always to push slowly down the pedal too have a goood result

and i have again a little fuel leak at the black box on the meetering unit when i puch it back to 11-11.5 on AFR before i had 12.3 AFR and no leak

what i don t understand is do i every time need 11-11.5 AFR on driving normal ( it s ok ) but when it boost i think is impossible to have 11.5 it every time stall a little bit to 12.5 -13.5 AFR when the car is boosting like full throttle on 1 gear...?

i know is the old ke jetronic
