i have my car back now and its running, i now have an intake, full 3 in catlyst free exhaust, 4 850cc inj. power fc, fmic. profec b2, and full non-sequential stock(rebuilt turbos)



at idle i notice that its been putting out a little smoke now and then, but the real problem is when i get above 3500-4000 rpms (usually full throttle) it puts out some heavy black smoke, im talking diesiel locomotive amounts, or some superduty truck. could this just be a nasty tuning issue or is somthing bad ( seals, turbos???)

ANY help would be aprecciated. i wont be driving anytime soon due to an ice accident but i plan on fixing the prob before its driving. thanks.........

Black smoke is never a good thing.



Sorry I can't help you with any more info.

black = fuel

My Bad, I thought blue was fuel. In that case it sound's like it's running very rich.

Blue is oil, black is fuel, white is coolant. Sounds rich to me.

blue=oil. white=coolant

Is it possible you haven't adjusted the PFC for those 850cc injectors?

And green means you're driving the cheech and chong weed wagon and it's on fire.
