Today I just got a list of the changed parts involved in the powerkit. The whole kit consists of 72(!) different parts, some of them are just little parts, others are larger parts like the brake calipers, front shocks, intercoolers, etc.
The number is even higher if you count the single parts like each screw, bolt, etc. seperately.

I just wanted to mention it, just in case somebody thinks it is just a huge rip-off and a simple software upgrade only.
