might be dumb question but I have a 2004 dodge ram 2500 4X4 diesel. Its the 325 hp engine. I know some basics of diesel and know that black smoke is good because it is burnt fuel. My dodge that i bought used seems to blow lots out exhaust especially when passing. but even in town if I hammer on throttle a little it blows out black smoke. (enough to make soot on back 1/4 fender and bumper)Is this normal and could it maybe chipped up without me knowing. will the chip make more black smoke or less? also i drove ford and chevys and their diesels dont blow much smoke if any.and its totally fuel related because my oil level doesnt even drop a bit between oil changes.My ? is how much does your 5.9 cummins smoke?.

 

black smoke is not burnt fuel it's unburnt fuel. and it's not nessacarily good. smoke usually means high egt's which can be harmful to the engine if you arn't careful.

 

black smoke is actualy unburnt fuel.

these trucks will smoke a bit stock. . .it is just the nature of the beast. will a chip make it smoke more. . .enough to shut down intersection

 

Mine stock, maybe a light haze if I hammer on it. Now with the edge thats a different story

 

I am still wondering why my 6.7 is blowing smoke. Not sure if it is a good thing but it runs good.

 

I can get a decent amount, I need more. hopefully when I call superchips on the 1rst that can all be taken care of.

 

i wish my automatic 2002 cummins smoked more...wtf! even with the edge juice with attitude it doesnt smoke much...

 

probably because you have a good air intake system on there it's getting enough air to burn off a lot of the fuel therefore no smoke. but that lso means ur egt's are lower which is a very good thing.

 

i got the same truck you do with 102000 on it and it is just straight piped and blows black smoke if i get on it.

 

it smokes a decent amount. so with a chip it will smoke more? and if so then chips arent good are they. why would you wanna add a $600 chip so that you can send out more UNBURNT fuel?
