If memory serves me right, the Active Hybrid 7 basically has the 4.4l TTV8 (same engine as the X6 50i and 750) but tuned to output 440hp and 480lb-ft. So basically they are offering this "Performance Upgrade" kit that provides the extra boost they have standard on the Active Hybrid 7 TTV8 engine to models that have the same engine but with regular power output...
If that is the case, I don't think that for this modest boost in power that there will be too many changes other than a software upgrade...
