Yes - the GW4D20 diesel and GW4C20 turbo petrol are modern, well-engineered platforms that handle conservative Stage 1 calibration safely. We take a careful approach on newer platforms, validating boost, fuelling and EGT behaviour on NZ fuel before finalising the tune. Great Wall engines share many design principles with other modern common-rail diesel and turbocharged petrol platforms we have extensive experience with.
Yes - the GW4C20 2.0T gains 20–35kW and 50–70Nm on Stage 1. For a turbo petrol ute, this improves overtaking confidence and overall responsiveness. The petrol Cannon is a capable vehicle in standard form, and the tune brings it closer to the performance expected from a modern turbocharged platform. We recommend 98 RON fuel post-tune for best results on the petrol engine.
A Cannon 2.0T diesel on Stage 1 typically gains 70–100Nm and 25–40kW. For a ute at this price point, that's a meaningful improvement in towing and grade-climbing capability. The gains are most useful in the 1,800–2,600RPM low-load range - where the diesel engine is working hardest when towing. Owners using their Cannon for regular towing duties report noticeable improvement in how the vehicle handles loaded situations.
On diesel models, yes - the extra torque reduces throttle demand at cruise, and efficiency gains of 5–8% are typical on highway driving. Petrol models are more dependent on driving style. For a working ute used on regular routes, the diesel efficiency improvement is a practical benefit. We're transparent about realistic expectations - the primary benefit for most Cannon owners is improved towing performance and drivability, with fuel economy improvement as a secondary gain.

2018 Subaru Forrester - Howick

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.
