Should. You'll have less pressure drop and see colder charge temps.

I've got a followup question: will it make a significant difference in air/fuel ratios? If I upgraded the IC on an otherwise stock car, would I risk running lean?

ECU will compensate for the temp drop and the increased boost. You won't have to worry about running lean until you open up the exhaust etc.
