No smart ass here. Air becomes thicker (dense) the cooler the air becomes. Your car was tuned in a relative humanity density air point. ( Flordia very high humanity and probably high 80 90 degrees) Now the colder air is thicker meaning there is a lot I say a lot more air being brought into the engine. The ecu thinks the motor is at higher rpms due to more air flow. Turn your boost up to compensate the richness, but don't do this because this = excessive boost pressures. It would help correct you air fuels ratio but will mess with other shiz it.
