When I start my FD whenever cold cold, little drops of something tend to escape the exhaust... My fd does need a tune though... could it be fuel? Anyone have a solution?

Its comes out black, not clear. Is that because of the exhaust? Should I be worried lol?

Its condensation in the exhaust. Its black because of the exhaust soot throughout the piping.

Yeah, it's normally water. If you have a main cat, cats actually turn hydrocarbons into water. Mix that with black soot in the exhaust, and there you go.

If anything, cars want a richer mixture when cold - a cold engine doesn't atomize fuel as well, and if you ran the engine on the same mixture as a warm engine, it would stall out.
