The Sport Chrono Package Turbo.... In the 911 Turbo models, under full acceleration, the maximum boost pressure in the lower and medium speed ranges is now temporarily increased by approximately 2.9 psi (0.2 bar). As a result, engine torque is boosted by 36 lb-ft to a maximum of 516 lb-ft for a limited period. (The 911 Turbo S models are configured to operate with a higher boost pressure level, which means that their maximum torque is always 516 lb-ft.)

The 911 Turbo models generate 500 hp at 6,000 rpm and 480 lb.-ft. of torque between 1,950 rpm and 5,000 rpm (516 lb.-ft. for a temporary period with the overboost of the optional Sport Chrono Package Turbo with dynamic engine mount system).
In the 911 Turbo S models, a modified valve control system and an adaptation of the engine management, combined with an increase in maximum boost pressure by around 2.9 psi, enable the power unit to produce 530 hp between 6,250 rpm and 6,750 rpm and generate a permanently high torque of 516 lb.-.ft between 2,100 rpm and 4,250 rpm to deliver even more power to the road.
So its buy the "sport package" or buy the S and get that extra 2.9 PSI all the time.
