Jet UP when it starts getting cooler. Go up 2 jet sizes front and back and see if it picks up MPH. As always, all cars are different. My car usually starts picking at around 65 degrees.

The best way to do it is with a weather station. This way once you've got the car dialed in you can adjust your jetting based on the changes in the weather.

If you don't have one, your body is a pretty good gauge...
When it's nice outside and you feel good so does your engine it wants more fuel. As the weather gets worse and it's harder for you to breath and move around its the same for the engine it wants less fuel.
