I know I keep posting this, but there's always someone else who hasn't seen this. GruppeM gained me 5.5 max wHP, and about 7.5 ft lbs of max torque, but clearly throughout the rpm range, HP and torque gains were apparent. See dyno:

Blue line is OEM intake; red line is GruppeM intake.

I dyno tested the 330i (6MT) before and after the addition of the GruppeM about a half-hour apart on the same day.
