Tuning And Smoking?

[Suspense]

hey people.. my r3gtst has the following mods...

GCG highflow

Z32 AFM

555cc Injectors

PFC

(and all the usual stuff)

& 250rwkw

Now my dilema is when giving it a fanging, i get alot i mean ALOT of black smoke coming from the exhaust. However my A/F ratio's are fine... level out at 11.8:1 (tuned with an external 02 sensor and Heat sensor @ exhaust end both in good condition). Just trying to get an idea of what can be causing this smoke on hard acceleration.

any idea's? i was thinking maybe the AFM, could be on its way out and playing up? but i have no clue... i also have a highflow cat, would this cuase it?

Yeah my car has the same phenomenon. My wideband reports high 11s on full boost yet I still have smoke happening. I'd try leaning it out to 12.5 which may clear things up but I haven't gotten around to it yet. I have no cat so this may be contributing to the smoke. The car uses no oil so I just say, thats the way it is...

yeah, my car doesn't use a drop of oil either....

I'm thinking its probably the fact that at 11.8:1 with a high hp/liter ratio will smoke where as other less powerful cars at the same AFR will not smoke.

I have a haze of fuel out the rear when driving behind mine car however it can't be seen within the car (rearvision mirror) UNLESS its at night with a car behind with its lights on.
