Hi, I'm impressed wth an update you've done to your Tesla. I currently own a RWD Model S and am on the market for a 90kwh battery. Was wondering if I can potentially procure a battery from the Dual motor Tesla or it has to be RWD just like mine is?There has to be updated also the firmware of the car to the "100D" version...And yes, this is done in factory mode, Tesla toolbox sw used.
