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...
I think the output from the V8 is the same, the difference is the use of two electric motors

BMW has officially unveiled their new X6 ActiveHybrid.

Powered by a 400 hp 4.4-liter twin-turbocharged V8 engine and two electric synchronous motors (rated at 91 hp and 86 hp), the X6 ActiveHybrid has a combined maximum output of 480 hp and 575 lb-ft of torque. This unique powertrain enables the X6 Hybrid to accelerate from 0-60 mph in 5.4 seconds, before hitting a limited top speed of 130 mph. More importantly, the hybrid offers a 20% improvement in average fuel consumption (in EU testing) and a CO2 emissions rating of 231 grams per kilometer.
