I see a lot of the local younger diesel truck guys around here in Bend, OR that have modified their trucks that make a bunch of black smoke out of the exhaust when they jump on the throttles, why is that Is that unburnt fuel? My current 2006 Ram 3500 4WHD is stock with a little over 140,000 miles on it now and I'm thinking of buying and using a tuner to help it get better fuel mileage when not towing and maybe a little more power when towing my race car trailer. Do all tuner kits make them smoke like that? I had a 1998 1/2 Ram CTD EFI 2500 2 WHD truck before moving up here to Oregon in 2005 that I bought a tuner module for it and it didn't smoke that I could see in the mirrors All comments and help welcomed

No all tuners don't smoke. Higher flowing injectors probably have much more to do with it and yes its unburnt fuel.

a good tune on a newer truck should not smoke. on the 12valve trucks, you do get the smoke before the turbo lights. Because there is limited control over varying the fuel rates. My 1st gen will smoke good if I jump on it hard, but once it boosts it clears up.

Yes, every teenage boy in my neighborhood all have straight pipe loud as hell diesel pick up trucks that are rollin coal as they call it. They take of from the stop sign on the corner of my street & you can't see anything for like 5 mins. lol. I guess we were all teenagers once but we used muscle cars squealing and smoking the tires instead to terrorize the neighborhood.

I have 100 horse power injectors and a edge comp box in mine... it only smokes when the engine has to lug from being in too high of a gear. I'm not into "rolling coal", but like the extra power.

You could probably pick up a smarty programmer for cheap that would let you play with a few parameters. EFI live would be the ultimate programmer but you won't need it just for better fuel mileage and power unless you were going crazy. My 06 ran 12.50 @110 and does not smoke much at all once I got the tuning all figured out.

My 2006 Ram 3500 4x4 4 door long bed single wheel is used to tow my race car trailer around 5 % of the time, the other 95% is running empty going to local places (less than 35 miles) and some times on trips from 35 to 300 miles I have kept track of the fuel consumption since day one, it is worse now than ever I had one stock injector replaced around 105,000 miles, what is the normal life of the stock injectors? I would like to keep driving it for another 150,000 miles Any suggestions on what to do preventive maintenance wise to get that done Thanks in advance for the help

I had them set at the same time I had the one injector replaced, probably around 115,000 miles. I should do them myself but I can't lean over the fenders on this truck motor now like I use to be able to do several years ago I remove the slide off front end off of my S/P tube chassis car now so I can do a leak down test and set the valves easier than leaning over the fenders Work Smarter instead of harder, correct I'm trying to learn that lesson and practice it every day
