Was wandering the same. Has anyone had this backfire like a bog or slow down from being too cold?

Depending on what EFI system and what it is looking at to make tuning decisions, colder can definitely be a big problem. Any modifier that is adding fuel based on water or air temp could make it too rich or lean. Open vs closed loop and how much you allow it to add/remove fuel. As long as you are you willing to adjust the tuneup and these parameters it could make a difference.
