Why Customized Chip Tuning?
Factory software is left very conservative considering all types of fuel quality, harsh climate conditions, and emission standards. OnlineChipTuning shapes the file you read from your vehicle according to your requests (for example: "High performance for Abarth 595", "LPG optimization", "Giulietta turbo boost").
Advantages of our customized service:
- Provides a more elastic power band by reducing turbo lag at low and mid RPMs.
- Increases rev limiter (in Abarth models).
- Reduces fuel consumption through more efficient combustion.
- Perfects the harmony between automatic transmission and engine torque.
- Minimizes power loss in LPG/Natural Power system.
- Strengthens sporty character in Abarth models.
- Provides premium driving experience in Alfa Romeo models.
- Increases daily use comfort in FIAT models.
