I heard bt original setting the fuel is very rich. is it true? I see my car's bumper very dark. it's like smoked by the exhaust. I'm only using the original double exhaust for 20V, everything also original setting.
Is it really bt fuel setting is rich? anyway to adjust it or reset it? sifus-sifus please advise.
