dyno #'s and track times on a h/c/i car I have a 2002 som z28. I just dynoed 372hp and 340tq on a mustang dyno. The car was huffing (blowing black smoke) on decell so the 110,000 motor will need to be freshend up soon. The car was running lean above 6000 rpm so my tuner checked the fuel pressure and found it dropping uptop. The tuner stated i needed a fuel pump so he had to set the limitter at 6000 rpm. (even though my hp was still climbing). I decided to run at atco raceway anyway and sure enough i was hitting he rev limiter on my 2-3 shift. 1. because of the 6000 rev limit. and 2. I had a smaller slick then what i tuned my car with. The car still ran 11.8 at 116 and 11.9 at 115. I think my car would have ran in the 11.5 or 11.6 range. I had hoosier slicks on ws6 16 inch rims. No weight reducton besideds the jack being removed.

Black smoke = excess fuel
blue smoke = burning oil
Sounds like you need to get your car fixed and have the tuner go back over everything. You could also have a vacuum leak if the car was showing lean but there was enough excess fuel for black smoke.
In my experience, it has to be pretty damn rich before smoke will be noticed.
