Overview
The 4.7 GranTurismo range is one of Maserati’s signature Ferrari-DNA platforms, combining a hand-built naturally aspirated V8 with a very emotional factory calibration. Because it is already highly developed from the factory, tuning is mainly about response, torque shaping, and smoothing the upper rpm sweep. A well written file makes the car feel more urgent and more consistent while preserving the linear delivery these V8 cars are loved for.
Key Features
- Ferrari-built V8 feel
- improved pedal accuracy
- cleaner high rpm response
- preserves linear powerband
- works well with freer exhaust systems
