Just saw this posted on Instagram, first test of its kind I've seen.
From what I can tell, they dynoed a stockish 335i xdrive with AWD (normal) mode on, and then switched to xdelete's RWD mode and picked up 28 whp (roughly 10%). I am just posting this for those who may be interested in the results.
