    Black smoke on a stage 1 wrx

    Its probably nothing, but my buddy noticed a puff of black smoke come out of my exhaust when I got on the car the other day. I am stage one using tp map.

    Anything to be worried about?

    Thanks

    Possibly carbon from unburned fuel?

    most tunes are designed to run rich for safety. that's all it is, is carbon from unburned fuel. no worries

    Hmm any way to remedy that? Would adding a downpipe change anything?

    The remedy would be to make sure fueling is on-point with a WBO2. Typically, a tuner will air on the side of caution and target richer AFRs if they aren't able to get proper feedback.

    Can I install a wide-band on the stock downpipe?

    Yes. You'd need to weld a bung between the turbo and the first catalytic converter. In order to do so, you'd have to remove the downpipe, at which point, you may as well replace it with an aftermarket unit (that either has a WBO2 bung built-in or you get welded in), if you're able to pass emissions with that.
