I recently purchased a 2019 Ram 3500 6.7 Cummins. The truck is tuned and straight piped. The past few mornings it has been around 25 degrees. I’ve been remote starting the truck. When it starts, it immediately starts blowing a good amount of white smoke. After a few seconds high idle kicks in and the turbo is extremely loud. After a few minutes the white smoke goes away and when I hit the brake high idle goes off and the turbo sounds normal. When I start the truck and it’s above 40ish degrees it doesn’t do this. I previously had a 2010 Dodge Ram 3500 6.7 Cummins that was tuned and straight piped and when it was cold it never smoked and the turbo was never sounded that loud. Is this normal?

Are you sure its smoke and not just normal steam?
Every truck will have steam at those temps even stock trucks. If its smoke then the tune is overfueling

The turbo sound depends on how it’s programmed, so it could very well be normal based on the tuner. Even if it’s stock EB programming the 2019 will close the EB more than the 2010 did on its own with the EB off.
As for the smoke it could be unburnt fuel or it could be water, have you tried smelling it? Usually white smoke right away is fuel and white smoke after a few minutes is water.
lol, I just saw the previous truck was.
Overfueling would be more black smoke, white smoke is unburnt fuel from incomplete combustion. Timing and/or rail pressure would be more likely culprits if the tune is the issue.

I bet your right about it being the tune I didn't think about that.
It definitely smells like fuel. Just worried me since my 2010 didn't do this and since I've not had the truck long.

How many miles are on the truck?
Did you do the delete? Or buy it that way? Know what tuner/programming was used?
155,000 on the truck. Don't know much about it. It was already tuned and straight piped when I got it and everything under the hood is still there. When I purchased it he said they used EFI Live to tune it and its tuned to a Towing tune. He said they also tuned the trans.

High altitude? Our family's 2014 Ram 6.7L tends to do it after being parked at two homes in Wyoming and Colorado. At above 8,000 feet in elevation.
