I have a 1994 F350 7.3L IDI Turbo Diesel 5 Speed. Can't put a chip in it. What are my options to make it blow more black smoke? If I'm moving and throw it into a higher gear so it has to work harder is the best I can do right now and it still doesn't do all I would like to do it. Any ideas?
I'm pretty new to the diesel world, so this might seem like a silly question. But why would you want your truck to blow MORE black smoke? I take that as a sign that it is not fully burning all of the diesel in the cylinders, but rather, blowing raw diesel out the pipe. Less power, less mpg, more pollution, and so on. What am I missing?
Have you stopped to consider that bellowing big couds of black smoke is drawing attention to you and the diesel engines in general? It is in fact unburnt fuel and you and me and your kids and mine and my grand kids get to breathe that stuff. It is no secret that I don't like all the attention we get and the smog regulations that resulted from all the negative publicity. As it is now us IDI's don't have to have any emissions equipment and I would like it to stay that way.. Keep raising the big black cloud and some one will notice and then we can all spend $$$ to comply or buy a new truck- neither of which I can afford.....End of soapbox.......
Turn up the IP or stuff a rag in the intake would be the quickest way to blow smoke.

Nothing, it shows you've got some brain-power!
I don't get it either. I never drove truck with anyone (including myself) that ever got their panties in a wad because their truck didn't smoke pulling grades. Smoke generally means the guy's too stupid to downshift and not lug his engine or he's badly in need of a tuneup.
What are my options to make it blow more black smoke?
As was said before, stuff a rag or two in the air cleaner duct.

I've always been told that a little puff of black smoke at when you mash it to the floor is acceptable, any more than that is just a waste. Take notice of the big trucks on the interstate these days. Very seldom do you ever see one anymore blowing clouds of black smoke out of the stacks. That is because drivers and companies have realized that it is a waste of fuel/money and it doesn't gain them anything as far as performance goes.
Now if I were competing in a diesel truck show or something and I had a OBD II truck that I could chip, maybe I would turn the chip up for a few seconds to put out a big cloud just for show. But for my daily driver, no thanks.
I put a smoke chip in my IDI last year, mileage went down and it didn't produce enough smoke. I put the stock chip back in.

My turbo pressure line is 1/16" ID... and it uses a compression ferrule. But disconnecting it won't make smoke, both because it's tiny, and because increased boost does not increase fuel output -- the DB-2 runs solely on the metering device when not at WOT or idle.
