The most likely explanation is simply that you're running leaner with your PCM re-programming but within the safety limits of the system, or that the added volume of air alters the MAP/MAF readings. Without testing for EGTs and O2 at the tailpipe, you can't say for sure that it's the kit producing the results.

An even better (and cheaper, from an energy point of view) increase to knock resistance by simply injecting water into the engine. This will allow you to run very lean with less heat and less emissions.
