Hartge official specs for their 550i tune
Quote:
360 kW (490 hp) / 5500 rpm 720 Nm (lb-ft 531) / 6400 rpm

Went down to Germany and installed an extra ECU at Hartge.
Now the engine deliveres
490 Hp (+ 83hp from factory) and
720 Nm / 531 lb-ft torque (+ 89tq from factory).
The improvement in acceleration is fantastic!
These are the figures before / after ( measured with VBOX ):
* 0-100km/h 5.1s /
4.7s
* 0-200km/h 17.5s /
14.5s
Needless to say, but I´m very satisfied.
