I have a 2000 Si, with a intake and exhaust. It black smokes on accel. Not a **** load mind you. But enough to soot the tip and be noticeable on accel by friends/coworkers.

Should I get a AFPR and drop the fuel or bump it up a little? I hate to ask questions like this that are below most of you. But please point me to a FAQ or something that
deals with fuel tuning.

And yes I am aware the correct way to do this is on a dyno, or with a wide-band.

I think I will get the car dynoed this spring/summer once I get a header as well. But this is for now.

TIA

a little black smoke is fine if you are getting on it the engine will drop the AFR a little richer into the low 14's high 13's so that there is no Detonation
