Has anyone have any good custom setting for the winter weathers. Truck runs great in the summer on my custom level 2 but now in our cold front it sucks, it shifts real hard and sluggish. I have tried all type of gas still the same but we only have 89 octane up here.

 

I was going to say that cold air is good for our trucks.....until I saw you were from AK.

I'd have to say run it on tow tune and run down the shift settings. But thats only my best guess. It doesn't get to cold down here in AR...nor much snow for that matter.

 

Well the cold weather isn't here yet, the high today was 26 and low was 9. But when it does get here this is what I am going to run:

lvl2 running 89 oct
shift firmness 1-2: 0, 2-3: +5, 3-4: +5
shift points 1-2: +2, 2-3: +5, 3-4: 0
timing: +1.00

Nothing fancy, but in the winter I don't need it. As long as the truck starts and goes through the snow thats all that matters.

 

im still running my custom lvl 3 at -50....
