Overview
The 957 Cayenne GTS is the most driver focused naturally aspirated model of the first generation facelift range, using a higher output 4.8L V8 with a sportier calibration from factory. ECU tuning builds on that character with faster throttle reaction, improved torque shaping, and stronger pull through the upper midrange.
Key Features
- Sportier throttle and pedal feel
- Stronger high rpm pull for NA setup
- Better part throttle urgency
- Retains GTS character with more punch
