Off topic I know - is there a way to see the max power output similar to what you guys with the P cars see in a non Performance S?
Not from the factory. That gauge display is only on Ludicrous cars, and only available in Ludicrous+ mode, and only after the pack reaches 50C.
There are a number of apps out there that can read data directly from the car’s CANBUS if you buy an OBDII dongle and adapter cord and dig into the center console area to install it. There’s a lot of data available that way, I’m pretty sure instant power is among the items.
