Should I worry about it??

[mhines81]

The truck is still new to me, and I have noticed a puff of smoke at start up. The temps have started to fall to 45 Deg. and less. It's just a puff on the cold start, and then its fine after that. Being a diesel Noob, I'm just wondering if I should check anything.

Thanks!

It will be helpful knowing what has been done to the truck. Also what color the smoke is.

Truck has SCT Livewire TS..only running the street canned tune..........stock otherwise. 95,000 miles

Smoke appears gray, maybe a little blue tint

mine gives a little puff like this, it also does it in the summer but its black.
i was told its from a combination of the tuning and the vanes of the turbo not open yet.

You need a monitor to watch battery voltage and ficm voltage.....Write Up: Monitoring the 6.0L PSD.
Do you have a ccv mod?

Sent from my phone that somebody didn't help me get.

Ummm,,,,,,,,,,,I do have a monitor..............The SCT Livewire TS.............Battery voltage drops to around 11volts or so at startup, and the ficm volts never drop below 48.

mine does the same thing...ONLY on cold starts and its black. From what I understand, its perfectly normal
