Excessive smoke
Just want a an answer from ya'll. This is what my truck looks like in the morning, these two mornings it was foggy with a high moisture content of course. Basically it smokes a little, then when it goes into the stock high idle, I get this. I do not have a cat. When I start going, there is no more smoke and when I leave work and it is 45 degrees out, it only smokes a hair, nothing like this.
So... excessive? or normal?

Some of the Folks who are running the SCT have reported some smoke upon initial start up, depending on the tunes You downloaded. Try returning to stock and see if it still smokes. Are You running 2 stroke oil in the fuel? Mine smokes a light blue smoke upon start up when I run the 2 stroke. Use your SCT to check for any DTC's also. Hopefully You don't have a turbo seal going bad or an injector issue.

The program I am running is from Innovative and it is a normal street tune, nothing excessive. The only DTCs are from my EGR delete, the normal two, I checked the other day.
I hope I don't have either either. It does not rough rough on idle, only extreme cold start, like zero degrees. I hear an injector causes a rough idle. My boost is very normal, gets to 29 when towing and have it pinned up a hill. Other than that, does not really get over 20 psi. It runs great now, just want to ensure that amount of smoke is not indicative of a bigger issue yet to come.
It is out of warranty so I hope there are no injector issues.

No two stroke oil, that only goes in my snowmobile. LOL I do use Diesel Kleen every tank, white bottle this time of year.

When you drive it when it is smoking like that and if you lift of the throttle does it seems to puff out more smoke?

I haven't taken the tune off yet. But after I start driving, the smoke goes away immediately, no puffs after letting off throttle or anything. Of course the engine is cold so I baby it the first 10 minutes or so.

My truck does the exact same thing, when it is cold outside. a whitish smoke idleing in the morning, then goes away quickly once i start driving. I'm not saying this is normal, but I have not been the least bit concerned about it. The truck has been flawless for the first 50K

Mine whistles a little as well when the high idle kicks in.

my advise is stop the 2stroke oil, return the truck back to the oem tune, and try it. also test fuel pressure and perform any repairs reqired to get that inspec. test the ficm voltage. ohm out all the glowplugs (do not use a test light) if all that is good then most likly an injector concern.
