Reflashed two weeks ago and still blowing white smoke?

[03powerstroke250]

I had my truck reflashed prolly about two weeks ago. It stil idles a little rough and blows a puff of white smoke. If you try to rev it up before it is warm it will blow a stream of white smoke. But if you let it idle for about five minutes you have no problem with it. Any help would be appreciated.

I don't know about puffs, but if it starts to blow streams of white smoke it's probably the egr cooler. If it get's worse, I would say it definately is. But don't listen to me, because I don't really know what I'm talking about so here's a

normaly you won't get smoke from the egr cooler...you get it when its burned...the egr cooler its heated and evaporated...i would say that its the injectors...you could get out and smell the exhaust if it smells like diesel then its the injectors just warming up...if its sweet and smeells like coolant it could be the egr.....or wose head gaskets....

If it were the head gaskets wouldnt it blow the smoke all the time. Is there any other way i can test the head gaskets?

sounds like a turbo or EGR cooler going south to me....

is the smoke pure white...or is it blueish white???

[03powerstroke250]

pure white no blue at all. but when it gets warm it runs great and no smoke.

Do youthink that i should take it back to the dealership?

I got out and smelled the smoke didnt smell like coolant at all just diesel fumes. do you think that it is just a glow plug or an injector warming up. and input is appreciated.
