Power delivery becomes more refined thanks to optimised spark timing and throttle progression. This Stage 1 file elevates the driving feel by improving response to pedal input, particularly in Sport mode. No emissions components are removed or altered, making it ideal for naturally aspirated performance on non-public roads.
