Default blue smoke over 2000 rpm?

i just bought a 94 cummins wit 82000 miles on it. my question is when idle it runs mint i get on it a little and smokes black but wen i really get on it once it gets past 2000 rpm it pushes blue smoke and sputters? idk what it could be injectors maybe? i don't no much about cummins yet but soon i will.

I would imagine its something simple, the truck has no miles its like new with that low of miles. If you don't know about something, then this is the place to come.

yes it is, that just sucks if you need injectors at olny 82000.
id save up for some stage 3s or 5s and ugrade your turbo.

i got a #10 and i like it.
you could go bigger tho.
i was gunna get a #0 but i didnt want to deal with adjusting the governor and
I would get some injectors or atleast get them tested.
with the fuel plate and injectors your definetly gunna need some guages tho (egt,boost,trans temp)
then youl just need some air upgrades. maby an afe intake and a adjustable boost elbow or just pinch off the line totatally
theres alot you can do with the 12vs just find someplace to start
