Yes - the PureTech and BlueHDi engine families are shared with Peugeot and have a well-established global tuning track record. Both platforms have clear factory headroom, and Stage 1 calibration keeps boost, timing and fuelling within safe limits. We validate on NZ fuel grades and log the result before delivery. The BlueHDi in particular is a robust diesel that responds cleanly and consistently to calibration.
Yes - diesel tuning on the BlueHDi often improves fuel economy by 6–10% on motorway routes. The extra torque means the engine operates at lower throttle positions to maintain speed, reducing fuel demand. For anyone who regularly commutes or does long highway journeys in a Berlingo or C5 Aircross diesel, the efficiency gains alone can justify the cost of tuning over a reasonable ownership period.
A C5 Aircross with the 1.6T PureTech petrol gains 25–40kW on Stage 1, making a noticeable difference to overtaking and motorway confidence. A 2.0 BlueHDi diesel gains 30–50kW and 70–100Nm, which is significant in a family SUV - the car pulls much more cleanly when loaded with passengers and luggage, and motorway cruising becomes more relaxed as the engine works less hard.
Yes - the EAT8 shared with Peugeot handles Stage 1 torque increases well. It adapts to the new power delivery without issue in most cases. A transmission tune can sharpen shift response to better match the engine's improved calibration, but this is optional for Stage 1. We assess on a case-by-case basis and advise whether a combined tune is worthwhile for your specific model and driving style.

2020 Audi RS6 - Takapuna
I brought my diesel ute in looking for more pulling power, and the team at Auto Tuning absolutely delivered. The difference in low-end torque is massive; it now hauls heavy loads up hills without breaking a sweat. The biggest surprise has been the improvement in fuel economy during my daily commute. A proper, professional tune.
