It's torque that matters, bmep at its highest level. Power is just a multiple of bmep. Mind you, bmep is a calculated number but it represents real force.
If colder air results in more fuel being added then superficially higher bmep should result. However, the engine can't take more bmep than the detonation limit allows. Since the knock sensor operates at peak bmep already and at all temperatures then colder air can't make more power. The ECU retards ignition (or reduces boost) so the supposed more powerful air fuel mixture develops exactly the same bmep as the thinner air fuel mixture at higher temperatures.
It seems simple to figure out but it actually gets quite complicated.

Say it in simpler terms, are you saying the ecu pulls timing when it sucks in colder air? Are you saying the ecu doesn't use the colder air charge to extract more power out of it?
It sounds like if you are saying is true, the opposite also should be, the warmer the air intake, the more ignition timing it advances then, right?
EDIT:
You know what, fuck it, you're just a troll on here. You go one about the car's handling again (which seems to be the only thing coming out of your mouth) in this thread which has nothing to do with making more power in colder weather anyway.
