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
