I put on my egr and 5inch straight pipe no codes and running SW 3 and I still have no smoke. I hear everbody rolling more smoke than the old 5.9's but mine doesn't smoke a lick any ideas why?

 

Mine dosent smoke on SW3 Either it starts smoking on sw7 Through sw9 but you better be prepared to install a new clutch.

 

I also run on Level 3 with no smoke.

I have a stock tranny am afraid to goto Level7 or beyond.

 

on sw 9 still not smoking like a my old 5.9. it is smoking alittle.

 

if your looking for smoke you should check out the XRT....the 175 tune really dumps some fuel

 

Smoke is overfueling... So truthfully, as cool as it is... Its bad.

I cant blow any good smoke until SW9...

 

or throw the water/meth to it. we did a snow stage 3 mileage max on a long bed mega here in town and that thing shuts down a freeway with all the smoke with smarty on 7, tq mgt 1, rail 2, timing 2 and 3 stages of water (70% water 30% meth). plus we dropped nearly 300 degrees off the EGT

 

I just did a 4" DPF delete and 6" stacks and my 08 Rolls the Coal all day on SW5. On my first 20 mile trip to work the top 1" of my stack is all soot! Inside and out!

I hear alot of guys NOT removing the knock catalyst right behind the turbo, that thing traps the soot and smoke big time. Im straight pipe from the impeller to the tip and at 50 mph in 6 gear going up a slight grade it was a smoke trail behind me the whole way. And if you down shift and put some to her she belch's a nice cloud then clears up to a noticable trail of smoke.

Now I aint trying to over dramatize, it dosent look like those trucks in the mags pulling a sled with 100psi and enough fuel supply to make Chevron enveyous blowing a massive nuclear cloud of Cummins in the sky.....but she rolls some very noticable coal!

 

I agree I have heard that

 

marco tries to keep smoke down. me 14 is less, hardly any smoke up to 7. over a 100 plus hp and no smoke. level 9 will smoke some. great job marco
