Just noticed this AM that the TM Design Studio for the Model S had a few subtile changes.... Right at the beginning there are two buttons ... MAX RANGE and MAX PERFORMANCE Invoking either of those buttons, configures either a 90D or a P90D. Next change is that the 85, 85D and P85D descriptors blocks do not change to 90, 90D or P90D when you choose the RANGE OPTION or LUDICROUS MODE. The RANGE OPTION box, if chosen or auto selected, now shows you which 90 you are configuring. Any other things different that I may have missed?
