Proper break-in, warm up?
Is there anything special that has to be done to break in a 6.4L/DPF?
I've got a truck lined up and it has 220 miles on it. I can't control what happened in those miles, but I can do whats best for it once I pick it up.
Does running it hard (petal to the metal) do anything bad to it right off the start? My guess is anyone that test drove this one probably goosed it a few times.
How about normal warm up? Isn't there a certain egt that should be reached before driving? Likewise, a cool down period after a drive?

NEW VEHICLE BREAK-IN
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed to allow parts to adjust
themselves to other parts.
Drive your new vehicle at least 500 miles (800 km) before towing a
trailer. Make sure you use the specified engine oil by checking the engine
oil specification chart under Engine oil in the Maintenance and
Specifications chapter.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) of operation, since these
additives may prevent piston ring seating. See Engine oil in the
Maintenance and Specifications

Regard to warm up and cool down, generally it needs very little. Over time you will feel that with a 30 sec idle and then normal driving, the engine feels a little tentative. Oil temps above 150 and everything is "wide open".
In the winter you will know. The cold weather strategy will kick in and high idle when you start up to get the oil up to a certain temp before it will idle normally. I don't remember the exact temp but it is around 85 degrees (I think).
Cool down? I have run mine plenty hard and always let it idle for a minute or two. EGT's are about 365 at idle in normal outside temp weather. They reach 1200-1300 for extended periods of time when towing uphill. Big difference.

When you get the miles on it, then I suggest that go for a tow. Ideally because you need to, otherwise excuses work pretty good too. A good diesel is designed to work and work hard.
Those that run it have fewer issues then those who baby it.

For many years, and many miles I have done the same thing, and never had a problem.
I start my truck and let it idle about 1 minute, then drive it moderately for about 5 minutes before using full throttle.
I try to not push it too hard say the last minute of travel to my destination, then let it idle for about 1 minute and shut it off.
Break in has always been regular driving for me, and change the oil earlier than usual as the only difference.
