2007 5.9

Otherwise stock as far as I know--bought the truck @ auction a few months ago.

Been noticing lately it smokes a good bit when you roll into the throttle on acceleration. Air filter is fine, fuel filter is fine, all the maintenance "stuff" is done.

Kinda dumb when it comes to the CR engines...wondering if they exhibit a good bit of smoke in stock form, or if there's something I need to be looking for?

By "a good bit" I mean it's enough for my 74 year old father to comment about how it looks like his old pumped up 444 Cummins....it's a cloud for sure.

Is this normal?

My truck with no power adders doesn't smoke,
slight haze. If I add timing with smarty, I
will smoke out the intersection, Tight converter
large sticks.

I wouldnt think that they should smoke much at all. The ones that I have seen around here dont smoke except for a slight haze and also my 02 24V all stock cept for 4" turbo back and a bhaf just puts out alittle haze too. You might have a intercooler boot leaking or something like that. And any codes?

Mine will toss out a decent cloud if I haven't leaned on it in a while and stand on it pretty good. Otherwise, its hardly noticable. If I do back to back pulls only the first one will leave a smog pattern.

Diesel Dawgs Performance is the only diesel vendor I have shopped with in the last 10 years who hasn't tried to screw me over. Thanks, Luke!


Who do I think I am? Well, best guess is I'm a thin layer of charming topped with some funny sprinkles, surrounding a creamy center of raging arrogant asshole. Close? Cheers.

was it a re-po? maybe someone had a programmer on it and didn't get to remove it before it got gone..... or they put in aftermarket sticks after the stockers took a crap....

does it feel faster than any other commonrail you have driven?

My 06 would make a huge cloud of smoke when you got into it if it had been driven easy for a while before. I believe if you add the tube off the bottom of the airbox it will help with that. I never tried it on that truck, but had heard it would remedy the problem from others. My 03 does not smoke at all.

My '07 smoked more stock than it does now with a Smarty Jr. on default SW1. Definitely had a good puff to it on the low end, stock.

It's beginning to look like the 04.5 and up trucks are smokers out of the box.

I will look into the airbox tube mod, thanks Matt!

Of course this all depends....bought the truck for dad and he kinda likes the smoke now so WTF?

i have a 05 cummins 6spd an stock it wuldnt smoke much/very little if any an when it did youd have to be matted redlining pegged plum out otherwise i found you culdnt make it smoke excessivly but add a box or programmer an thats a horse of a different color hope this information helps

If the injectors are worn, it will smoke worse...mine did.
