hey all..I have a D&D exhaust can which isnew on my f4i, Had an oil change recently..It looks like theres alot of soot inside thetail of the can. I am runninga pciii usb with a micron map since there are no D&D maps for the f4i on the site..Its not like a black wet soot, just alot of buildup..You think its running too rich or lean...and can I adjust this with my pc3 by bringing the lights up or down? all 3 are in the middle right now..tia

 

I don't have a PC but dont think you need to worry about the soot.

 

i also have the d&d on mine w/the pciii mine does the samething and its been on there over a year & no proublems yet
