Good day, i have a 2004 Rover Streetwise 2.0 TD that i wanted to get remapped. It has a Bosch ecu code MSB101151. Is this ecu tuneable via the OBD port or does it need rechipping because the tuner says that it has a chip that would need to be removed to be tuned and it can only be tuned once then its good for the bin? Any replies will be much appreciated. Many thanks.
