I have the steeda CAI with preditor CAI with 93.Car is running good but i have noticed a little soot in tailpipes.My fuel parameter are at 0% and 0% set on the leaner side of the scale for both RPM ranges.Anyone have the same and know if i can lean it out more?Dont have anyway to test right now.maybe someone else has same setup?

 

I have the same on my exhaust tips. I'm not really concerned though, unless some think I should. My A/F is 12.5
