running rich or something else?

Well, we all know that black smoke out the tail pipe means you are running rich. While doing a second gear pull today, i notice a hell of a lot of smoke in my rearview. As did my friend who was following me and he states it was a pretty dark black. Now the wierd part...my wideband didnt read higher than 11.3:1. Other then that i never noticed any smoke coming from my tail pipe. What do you think?

where you dataloging anything?or do you just have a wide band. Do you know what your injectors where runnng at(Each of them), What's your timing? spark plugs clean?, Pump gas? Race gas...?

Could be simple fix or ....?

I was not datalogging at the time and this was on pump 93. I will be replacing the spark plugs tomorrow before i hit up island dragway. They have been on the car for a couple months now.

I put brand new ngk's, set the boost down to 19, and went 13.0 @ 103.6 today. One of my plugs must have been fouling cuz the problem is gone and car is running smooth.
