Gets a little sluggish from a stop

Hey guys I’m new here and new to duramax trucks. So I bought a super clean 05 lly 2500HD Silverado. I love the truck completely. But I’ve noticed from after driving for about an hour or more when I leave a stop light or sign well basically from a stop the truck starts acting real sluggish and a little bit of blackish smoke comes out with it while sluggish then it clears out and runs fine. But it’s from almost every stop after that till I shut the truck off for a while. So I get the truck home I have a Snapon ethos edge scanner all the temps look good no engine codes the only code I do have is for the hvac re circulation function. So I ran a balance on the injectors and I have 3 injectors going from 0 to +3or+4 and the other 5 are -1to-4. I know that there all supposed to be under 0 at least I think like I said I’m new to duramax trucks. Would that be my issue. Thank you guys and sorry for the long post I’m just trying give a detailed image and amount of information for someone who may have an answer to my problem. Again thank you guys

You've given a better picture than many do. Glad to have you here. Do you know how long the truck sat before you got it?
