Truck Running Poorly, Suggestions Please

[Tylor McMurrian]

I have a 2013 2500 with the G56 and it has the follow mods below.

Air Dog Lift Pump
ARP Head Studs
Banks Monster RAM
60% over Exergy Injectors
RaceME Ultra Tuning
S&B cold air, and some other small things

It runs really rough with lots of white smoke at first start up no matter what temperature outside then clears up after two or three minutes.

While driving anything under 1500rpm the truck misfires pretty severely.

It has been running some what poorly for a couple months now but I just assumed it was because it never got warmer than -10 and three days ago it got much worse than it had been but it’s been in the 50s and 60s for the last week any suggestions would be greatly appreciated.

When was the last time your fuel filters were changed?

If changed what did they look like?

Have you done anything else to the truck that may have caused this?

Did you notice this happen after filling up with fuel at all?

Have you tried any additives as of yet?

I changed my fuel filter and water separator around 5000 miles ago they are canister filters so I’m not sure how dirty they were.

I also ran the tank down to almost empty and used diesel kleen with the fresh tank the only thing that changed was I just got back from a 1500mile trip.

Hows your rail pressure?

I have this issue when a tune doesn't set correctly like when i go to set it in 12 valve mode it just dumps fuel and misfires.

You have any codes?

Are you rough on the truck?

Sounds like injectors.

You may have just worn them all out and they are leaking when cold.

The newer injectors seem to not last as long as they once did.

I just reread the post.

You are running rich as too much fuel, not enough heat.

How has your turbo been?

Any issue?

Exhaust brake still work?

Is the air filter filled with dirt?

Have you serviced the CCV filter?

Are you making oil?

Keep an eye on your coolant level also.
