I have read it and there is this message:
CAUTION! If a dealer or installation facility has installed and programmed your vehicle, be sure to obtain the USB cable and PC3 file from the installation facility. It is be required to restore the previous calibration or make modifications to the vehicle configuration after the vehicle has been programmed.
I think that I can always revert back from Dreamscience to stock and use drift stick but I am afraid that if I flash/calibrate Dreamscience tune/remap with drift stick calibration I cant get back to original Dreamscience tune/remap and then back to stock.
Mountune webshop sells drift stick so I think it will work with they tune/remap but as Dreamscience have no idea how this works and they cant confirm that I can try something I need to skip this product. It would be so cool but it is expensive decoration if I cant use it 🙂
