I know the basis of why when the ambient temp is cold the car goes much better, but I'm talking coolant temp/engine temp.
I felt the intake pipes while I was stopped when the engine warmed up, and they were still cold. So when the coolant temp is raising, it's not having any effect on the intake air temp as there is little to no heatsoak of the intake area. It's just a magical point when the car decides it doesn't want to pull like it should.
