To downgrade from 3.71 you would need pandoras battery.

None of them, they don't work on 3.90M33.
For 3.90, you'll need to use the Universal Unbricker. Check it out in the FAQ guides.

I need a Porsche 911 Gt3.

If you read the guide it will explain it all - Whatever you decide you will need a pandora, and more than likely DC7.
