Yes - Opel's SIDI turbo petrol and CDTI diesel engines are well-proven European platforms shared with Peugeot and Vauxhall. They have a solid global tuning track record. Stage 1 calibration stays within safe operating limits, and we validate on NZ fuel grades with boost and fuelling data logged before delivery.
Yes - on CDTI diesel models, fuel economy improvements of 6–9% on highway routes are typical. The extra torque means less throttle at cruise speed, which reduces fuel demand. For an Opel used as a daily commuter or for regular highway trips, the efficiency gain is a genuine benefit. In urban driving the improvement is smaller, but throttle response improvement still makes the car easier to drive.
An Astra 1.6T SIDI on Stage 1 gains 25–40kW, taking it from around 147kW to 175–185kW. A Grandland 2.0 CDTI diesel gains 30–50kW and 70–100Nm of torque. For a family SUV like the Grandland, the diesel torque improvement makes a practical difference in everyday driving - motorway overtaking, loaded driving and grade climbing all become noticeably more confident.
No - ride quality and refinement are mechanical characteristics unaffected by ECU calibration. The tuning changes how the engine delivers power, not how the suspension or body behaves. In practice, most owners describe a tuned Opel as feeling more confident and relaxed because the engine responds more willingly - which can make the car feel smoother in traffic and more composed on motorways.

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.
