I would assume from what I have read that black smoke means it is running rich and dumping fuel that can't be burned.
I just got an SCT x2 and my friend says the more the black smoke the better.
Can Eric or someone clear the air? (of the black smoke!)

Will let the tuners respond,
but my understanding for the smoke is your engine is a big air pump...
add fuel and pressure and it burns... more fuel and it burns MORE
with any given engine, the tuners can't modify your "air" (intake and exhaust) but they can modify fuel delivery....
for a given amount of air and pressure, more fuel = more power
(to a limit) until the fuel reaches a point where it no longer burns...
but the tuners don't know at which point a given truck will not combust the fuel and they want to make sure the engine's power is not fuel limited !!
smoke is unburnt fuel, so it goes out the exhaust...
More air with better exhaust and intake,
or some "fake air"
nitrous will burn more fuel...
have heard some that think that unburnt fuel also lowers your egt's a bit...
not sure about that, but it's a theory
