Start up Smoke

[zeuss]

Try to make simple. 3 weeks ago truck didn't want to start at 30 degree. when did it would chug and smoke like heck. Took to shop , glow plugs good, relay replaced, new orings on injectors installed. They sent the injectors out for testing and the result was they were down about 10 percent while higher rpm and good at idle. They recommend replace but i didnt caue ran good and 120k on them. Got truck back and starts at 0 degree without plugged in. But it smokes like one guy said, a 4020 deere, til warm. Then cleans up and is fine. It doesnt chug anymore since new orings and starts fine. I am running in stock setting on chip. When in this setting am i actually in my pcm or a program put on chip. Any input would be appreciated. THanks.
