This is total BS.

1. There is no setting to unlock power inside the DME. Forget it. The PowerClass byte is simply a validation byte to insure the Powerclass of the flashed tune matches the Powerclass in the car. This is the value that causes the DME to jump into limp mode if you flash a 330 tune into your 325. That's all. Changing the value, if you could, will not do anything.

2. The Software does not allow you to change the powerclass coding on any DME that has more than 10 hours recorded. Try it, it NCSexpert will write the code but it will not "stick". There are ways around the security but it's not going to happen like Mr. BMW Quack claims.

Each factory tune has something like 100 maps that are specific to that vehicle and powerclass. Fueling, Torque management, VVL, Ignition etc They are all modeled and matched for a specific power output, No way will a single switch modify 100 maps to realease more power.

If you have a 325,328 etc the best way to run the highest output tune created by BMW is to visit Bimmerlabs and download the tools / files that will actually work. Will take less time than watching the Quack show.

Thanks for the explanation. I, too, had my suspicions. For us who didn't go through the whole exploration venture learning these things from behind the scenes, there's no way I could validate/vindicate it. But glad you can help pointing it out, though. Thanks again.
