so i'm running bio diesel and i put so regular diesel in my rear tank and ran on it for a while in hope of getting some black smoke. well i got none!!! now when i switched back to bio diesel i get a bit but its just a short shot of it . how do i make it smoke ???? WHAT DO I HAVE TO DO??? its got a stock intake 4 position chip and 4 inch straight pipe? is this good or bad? i heard the reason diesels black smoke is because the lack of oxygen to fuel mixture??? is this true?

you need injectors to get any serious amount of smoke. look into diy kit from rosewood diesel.

well make sure you got an aftermarket dp if you just straight piped the factory exhaust but actually mine smokes pretty good now with a full intake full exhaust fpr shim edge evo on extreme and my map sensor unplugged.

btw i dont know why but when i unplug that map sensor it smokes literally twice as much compared to when its in. i like it! i can finally smoke out ricers pretty good and actually did yesterday

ok cool. ya i'm going to get a cold air intake and chop my muffler and put a stack on it hopefully that will give me better flow and more air. i just think it looks bad a$$ comming down the ramp onto the highway blasting black smoke everywhere! i would get new injectors but i dont have 1500 to spend on injectors i'd rather get a levling kit and stacks than that. so anything other than injectors?

Really depends on what year truck you got...if it's an old body style (94.5-97) you're gonna need stage 1+ injectors to blow some serious smoke like the newer trucks...

Full turbo-back exhaust (to get rid of the crappy downpipe if it's an O.B.S.)

Lastly what kinda chip are you running? If it ain't a Tony Wildman TS chip or a DP Tuner chip, then you're not gonna get a whole lot of smoke...

You can think of the off-the-shelf tuners as "tuners with training wheels"

Good luck finding injectors at a reasonable price. My brother recently had a new set of injectors put in his 2000 and the injectors were about $200 a piece plus the labor to put them in. Out the door it was around $2,000. Just an FYI.

I think I've got a pretty good idea, but where is the MAP Sensor located?

dam i umplugged the map sensor and it was throwing black smoke pretty good 10 times more than it was before. hell i'm even rooling it on biodiesel and i didnt kno that was possible all i ever got out of bio diesel was grey smoke !!! thanks guys ... isnt the map sensor the thing that tells the engine to adjust the fuel mixture???

well you buy the kit from them for $250, and you can either pony up the extra $225 for them to machine your injectors, or get a machine shop to do it but i recommend letting rosewood do it. btw the guy that runs the company is on here DZL JIM. after that you can install em or pay a mechanic to put em in. on the mileage im not sure, maybe with a stock truck and just the basic upgrades and diy inj. you might lose a little BUT if you got that plus custom tuning from Wildman yes you should see good mpg increase.
