lol you basically re-phrased me.
It’s a very similar principle as to why your car is more peppy when it’s 32* outside as opposed to 92* outside. You could have 20% humidity both days and I’m pretty sure your car will run much better on the colder day in terms of throttle response, etc. Unless it’s just Maxima’s…which I doubt lol.
Lower temps = better car performance. I’m sure humidity plays a role, but so does overall air temp.
