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 help
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? help
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 confused
All comments and help welcomed up

No all tuners don't smoke. Higher flowing injectors probably have much more to do with it and yes its unburnt fuel.
I never learned to count my blessings, I choose instead to live inside my disasters.

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.

Yeah, a lot of the guys seem to take their tuner and ramp the fuel to max just to push as much smoke as possible. I guess they like buying extra diesel.
