stupid question- warm up temp

[Yellowsub1962]

I've read all over the place not to build boost on a cold engine. I understand this part, but where is the line for "cold" vs "not cold" on a 6.0? Is this typically "operating temp" or something like 50-60 degrees out. I work back in a canyon, and have to pull a relatively steep 1/2 mile or so grade immediately (like 100 ft from where I park) to reach the main road. When I work late it's 40-50deg out and I can't sit and let the truck Idle too long at 2am to warm up, and a high idle is really pushing it (neighboring ranch). Most of the time I can keep the boost to around 10psi (on the factory gauge) for the climb then just barely cruise it down the road till it warms up a bit. Is this acceptable? What is ideal?

You will be just fine. You will not hurt any thing by going for it. Try it and if your truck will take it, then go for it. Mine only needs a few seconds when it is cold (22° F) and the truck will move out without complaining.

Just take it easy like you are and you will be fine, Its when you run her hard when shes cold you will hurt it.

She'll move if I ask her too I guess it's the oil to the turbo that I'm concerned about... so it has enough lubricicity at anything over say 30 degrees?
