How long to warm up?

[69hemi]

With cooler mornings I have noticed that my F350 dually will stutter and not up shift as early until it is warmed up. Do I need to let it idle for a while or am I looking at another issue? Many thanks

Mine is the same. Plugging it in speeds up the progress.

I have a Scan-gauge in mine and monitor what I can and I don't move mine until she is at least 100*F, seems to help it out. Just my 2 cents worth.

I also wait until its about 100*

It is around zero here in the mornings and I let mine idle for a few minutes than take it easy for the first few miles.

Once my tft reaches 75 degrees on my SCT Livewire I'm good to go.

At what night time low temps do you guys start to plug your trucks in? We hit 43 this morning and I am wondering if I should have plugged it in last night. Its not a DD but I am heading up the mountain today.

I let mine idle till she's around 130.

Couple nights ago was the first for me this season forgot how nice it was to start a warm truck. It was about 40 here last night

At 40 degrees just a minute or two is necessary. Hell you dont even have to plug it in if your FICM is good.

I usually dont plug mine in until it hits 10 or so.

And then its warmed up long enough to scrape the windshield if needed
