Looks like ALL Teslas (S&X) come with the 72 amp charger, and it's software now.
High Amperage Charger Upgrade
Model S comes standard with a 48 amp onboard charger that provides up to 34 miles of range for each hour of charge. This is sufficient to recharge Model S overnight when connected to a common NEMA 14-50 outlet or Tesla wall connector. Every Model S benefits from Tesla’s expanding Supercharger network for travel over long distances.
This option equips Model S with a 72 amp onboard charger that provides up to 52 miles of range when paired with a Tesla wall connector on a 100 amp circuit breaker. Charge rates when connected to 120 volt outlets, 240 volt outlets and Tesla Superchargers will be unaffected.
