car is incredibly different when cold
im sure you all know what im talking about. when the car is cold; throttle response is fantastic, especially under light throttle blips, rpm's return to idle quickly, engine sounds nice and rough, low end torque feels very abundant. also, the car is louder. not just because it's idling higher. theres something else to it.
can someone shed some light? why can't the car be tuned to run this way all the time?

Good question about why can't they tune it to run that way all the time. It's common knowledge on the forum that our Stang's heat-soak pretty quickly.

Yeah it's really unfortunate too....
I agree, the stang feels amazing when I first take it out of the neighborhood on the way to work. By the end of the freeway it acts like a fat kid who just got done running 5 miles.

RE: car is incredibly different when cold
Just going to throw some facts out there....When air is colder, it is denser, which means there is more air per unit of volume when its cold compared to when its hot. There needs to be a certain amount of air to burn a certain amount of fuel, the ideal air/fuel ration, 12 parts air to 1 part fuel. The colder the air the more fuel it can hold per unit area, which means more power. Plus the colder air cools the engine down significantly more then hot air, that makes the intake temperatures even colder, holding more fuel, creating more power.

RE: car is incredibly different when cold
There are several threads on the board regarding the heat-soak issue. I plan on doing a few things to try and minimize it, such as:
1. Heat Extractor, Cowl or Ram Air hood
2. Electric Water Pump
3. Fluidyne Radiator
Steeda claims their cowl hood keeps underhood temps within 5 degrees of ambient, vs. the stock hood which evidently can raise up to 100 degrees above ambient.
