Nope. Does it smoke on start up? Smoke when you decelerate? What color are we talking about here? Blue,black, grey, WHITE????

Yup IDE take black over the others. How's your turbo spooling? Not low on boost or anything?

Might be catching early signs of the EGR valve plugging up.

Mine plugged COMPLETELY at one point and the symptoms I had was on occasion leaving a stop sign I would have zero boost, low power and just roll coal, also at highway speeds would get a slight haze on occasion. Cleaned the valve up and all that went right away.


Shouldn't take any longer than 30 minutes to pull the valve and clean it. 2 8mm bolts and some work with a lady's foot or prying tool of your choice.

iam running tsd tunes he said he turned the fuel up a bit but when i first got it, it didnt smoke that much and i drive it every day about 150 miles so i notice these things right away. Now that ya'll talk about the egr vale plugging up iam going to go ahead and clean it.

Couldn't hurt to clean your egr valve that's for sure.

you can buy an o-ring kit for it, comes with 2 o-rings and a gasket for the EGR valve, if your carefuly you won't need it, but worth having just in case.I think its like $5 or so from the stealership

and I forgot to note, when I had those issues my truck was bone stock at 55k Might want to check if your tune has the EGR valve turned off in the tune.
