stock tuning vs. custom tuning in the winter

[jay diesel]

Just wondering what everyone that lives in a cold climate does in the winter with thier tuning. Have been running extreme street for two weeks and seeems like mileage is dropping. Iam assuming it is because of extended warm up times and the amount of fuel this tune runs at idle. The out side temps are in the low 20's as a average. Wondering if I should put it back to stock for the winter. Thanks for your input

I run mine tuned all winter, MPG drop from extended idle, Hi idle mod, and running the truck in 4wd when needed for the snow days.

i had feeling that was the cause. I guess I will settle for 13mpg's until spring

I return my to stock in the winter. Helps mileage some.

just filled up the tank so maybe i will switch back to stock and see if it improves at all

Also, winter blended fuel will make a difference.

Mine stays tuned year round. Usually SRL

Or if its really chitty I will load the tow tune

Looks like a fuel filter with no membrane on it?
