5hp increase on new 2015 jeep srt question

Sorry if this has been discussed prior, but what exactly did they change on the 2015 jeep srt to gain the 5 hp from the 2014?

It would be in the "tune" only as nothing new was added to the motor. Maybe fuel/air ratio or possibly a cam phasing change.

Maybe the removal of the exhaust flap/valve?

Doubt it because of its effectiveness in reducing highway drone in MDS mode. It also helps the engine stay in 4 Cyl mode longer, I'm assuming because of slightly added backpressure.
