From what I've seen at the link below, it doesn't look like the additional hardware BMW will sell you is actually needed. Correct me if I'm wrong by the way!

1. Engine Control Unit (ECU) with updated software - If you can just flash the PPK tune to the current DDE, that's that problem solved.
2. Higher capacity Intercooler - This is the only thing that I'm thinking may be necessary? But 6 fins going to 8... Will that make a huge difference?
3. 600W electric radiator fan with improved frame for better airflow - I have never heard the fan on my e90 come on. To the point where the other day I used ISTA to test the fan and air flap things to make sure they actually worked!
4. Plastic air guide - What???
5. BMW Power Kit Aluminium Badge - Don't care
6. Other small parts - ?
I'd like to see if it's possible to flash the PPK to the standard ECU, but I'm a bit worried that it could brick the ECU to the point where I can't use WINKFP to flash the standard ZB back. I'm just one man and a car  I don't have any ECU's lying around, and would have to get a new DDE, CAS and key if it all went wrong 
If it failed to flash or just didn't work, is there always a way to flash the correct ZB back to the module? aka a backup plan |
I spent hours trying to find some more info. Many people tried and failed. In the end i found 2 people who claimed they've done it successfully, unfortunately both no longer available/active members.
To be honest, those who tried and failed made it unnecessarily complicated, so i used trial and error method
First attempt?? Successfully flashed and confirmed by reading ecu data in boot mode.
In the end its simple 2min mod of SP-Daten in notepad
