ok so i drive a 05 the new 600 cummins right... well i know the old 24 valves and 12 valves you could get the smoke real good by messin with the fuel but i have NO idea about that stuff unless someone showed me. My stacks are going to put installed next wed. when i get some free time and i was just wondering are they going to blow smoke at all since my truck is all stock. Keep in mind i am running straight exhaust too. If not how do i get alittle smoke and will it hurn my fuel milage if i have to turn the fuel (i dont want to have to mess with fuel)

Basically will the newer dodges blow smoke stock or do i have to do something AND what should i do. THanks for your help all you guys are very helpful.

 

nah, you wont see too much smoke... maybe alittle cuz it will be up in the blue sky and the contrast will show it *alittle* more... you will need a progammer to get smoke.
