I chip/tuner can only do so much on a stock truck. Yes, you can over-fuel to the point you loose power and create huge smoke....but you loose power. If you like raw fuel, add bigger injectors and keep the stock turbo. If you like power, tune what you have to the most you can, and add turbo/injectors and tune it for that...and have enough fuel flowing with big fuel mods to support the air map of your new turbo and you can get some serious black smoke on take off that will clear up nice once you get the turbo zinging....and your going to make power as well.

The idea that black smoke is power is not a true way of thinking. Like I said, you can jack up the injector timing to the point your pouring black smoke....but you are killing the engines real power curve and just blowing unburnt fuel. You can only burn so much fuel in so much time, and so much fuel with so much air......so your limited to the airflow of the stock turbo, as well as the fuel delivery of the injectors you have. Now if you could flow more fuel within the timing restraints of the engine you could make more power...to a point....because you would need more air eventually to keep the burn at near 100%. You see, pouring fuel on in a time after you know you can not burn it any longer is a smoke lovers dream....but its useless for power. A diesel fueled engine that is blowing black is blowing unburnt fuel, and just like a gasser.....you want to run "Race-Rich"...always allowing a bit more fuel in than you can burn.....a nice gray cloud is all that is needed. But much more than that is not too usefull.

I know, I like the idea of filling up the intersection with smoke....and a 6.0 Ford with a custom burn will do that easily for about 3-4 seconds until the turbo catches up and the burn rate nears perfection.......and at that point...you have made your point and are long gone from that intersection with a bunch of rice burners and gassers wondering what the hell kind of rocket just tossed you down the road like you were in a slingshot.... Once the airflow catches up, the smoke clears up.
