Does your car black smoke in boost?
So.... When I ran 12.5:1 AFR's it didn't smoke in boost, or at least not noticeably from driving and nobody ever told me it did. But with my car tuned to 11.5:1 in full boost, I can see a decent amount of black smoke coming out the back. I don't have a catalytic converter. Motor runs strong as hell, no knock, never uses oil ever at all whatsoever not even a spec or an infinitesimally small amount. But it black smokes in full boost. Like a diesel with a programmer, but not a sever obviously. Just wondering if I'm alone.
Do you have a catalytic converter?
What AFR do you tune for in full boost?
Any visible smoke at full boost?

I haven't seen soot out of mine even running slightly richer than I was (high 11s at 9 psi).
I have no clue if my bumper is black. but that's more from rich idle since the flow velocity at speed is high enough to keep it off your car. note: i idle at 14.3:1.

Nope, it's just the tune. Just curious if everybody has this to some extent. I never noticed till yesterday when I decided to look in the rear view mirror during full boost. Scary to take your eyes off the road when in full boost. I did a few 2nd and 3rd gear pulls and it's pretty repeatable.

this was shortly after i upped the boost from 9psi to 18psi... REALLY conservative tune, like high 10's AFR. no visible smoke (exhaust exits next to passenger side tow hook)
i do have a cat.
