Fooling the IAT to "lean the car out" only works momentarily. As soon as the 02 sensor catches on it will adjust the mixture back to stoichiometric. The 02 sensor is king of the [sensor] castle.
Timing is a different story. Like Daox said, a hot IAT reading will retard timing, if anything. That's backwards to what you want. That being said, I have messed around with fooling the IAT on many vehicles without any tangible success. The only engines that seem to respond well are diesels.
Actual hot intake temp is the key for some engines. But there again, many engines do not respond to HAI.
