Should I be concerned?
 

I've been tuning a lot lately and have learned a lot so far but still just enough to be dangerous. I just installed my EBC and car seems to run great. AFR's seem solid but every time I start it though it leaves a nice carbon trail on my garage floor. The car doesn't seem to be running overly rich so is this just something that goes along with having a China turbo with less than picky tolerances?.. doesn't smell like fuel so I assume oil is getting past the turbo seals.........just curious

Never mind. Reaserched some more and seems to be nothing to worry about.
