Smoking white after filter change
Well just finished changing both fuel filters on the 6.4 with the correct filters, pushed all the way down in there, facing the right way. Tightened them both back up nice and snug, turned the key on 6 times for 30 seconds started it on the 7th time, started right up for about 10 seconds then a little wrench came on and the truck shut down. Primed the system two more times again for 30 seconds and started it after the second. Now it will idle fine and took her out for a little run (2 miles and floored it for an 1/8th) couldn't see the smoke when I floored it cause its to dark out with tinted windows. however when I am in D standing on the brake and throttle it, it will smoke white with a tiny hint of black but mostly white. Any suggestions? No DTC anymore/wrench gone will idle/run fine

Read it, agreed its raw fuel, 99% sure its not injectors I was driving it around town all earlier that day with zero problems and there are no DTCs. Pretty sure its not EGR due to same reason. The only variable is that I changed the filters. Im not a tech so I very well could be wrong. I really don't wanna pull the filters again, swimming in diesel isn't the funnest thing. It isn't cold here (45*f) I dunno ill prime then again 6 more times and see if it helps.

no clue, as stated, why smoke on a diesel is raw fuel. i know you're tuned, is it possible the truck throwing the wrench changed something in the tune parameters? Perhaps go back to stock, and reload it?
