What ET has stated, but my thought is because now the intake is getting 100% cleaner and cooler air, not a mix of dirty hot exhaust gas aswell, the air can be compressed more, being cooler, hence slightly over boosting now due to a higher compression rate in the intake system.
I'm no mechanic, but that just made sense to me. Cooler air can be compressed more....
