Which engine gains most?
The 2.5T turbocharged, by a clear margin. The naturally aspirated units gain considerably less, since there is no boost to adjust.
What is Stage 2 for?
It is for cars that already carry hardware modifications, typically exhaust. Without them, Stage 1 is the right level.
How does it differ from the Cayman S?
The GTS is the sharper version, with more power from the factory. Each has its own entry in our catalogue.
