Yes - the Skyactiv-D in the BT-50 and CX-8 is a well-engineered diesel that handles calibration well within safe limits. Its high compression ratio and precision injection system mean it responds cleanly to boost and fuelling adjustments. We keep EGTs within safe margins and validate the tune under load before delivery. The BT-50 shares its engine with the Ford Ranger diesel family, giving us a deep base of knowledge on this platform.
Yes - the 2.5T Skyactiv engine in the CX-5 Turbo, CX-8 Turbo and CX-9 responds well to Stage 1 calibration. Gains of 25–40kW and 50–80Nm are typical, taking the CX-5 Turbo from around 170kW to 195–210kW. The improvement is most noticeable in overtaking responsiveness and highway merging - the car feels noticeably more willing and less in need of aggressive throttle inputs.
A BT-50 3.0L Skyactiv-D typically gains 30–50kW and 80–120Nm on Stage 1. This significantly improves its towing capability and real-world driving confidence - it's a strong result for a ute in this class. Owners who use their BT-50 for towing regularly report that grades that previously required dropping two gears can now be handled in a higher gear, which reduces transmission stress and fuel consumption on long runs.
On diesel models, efficiency often improves - more torque means less throttle to maintain speed. On petrol models it depends on driving style. What the tune reliably improves is the efficiency at which the engine makes power - you're getting more output per unit of fuel at a given load. If you drive the same way post-tune, fuel consumption is similar. If you use the extra performance enthusiastically, consumption will increase accordingly.

2018 Subaru Forrester - Howick
I was thoroughly impressed with the friendly and efficient service at Auto Tune. They transformed my car’s performance while maintaining reliability, striking the perfect balance. The difference in the driving experience is night and day, and the entire team was a pleasure to deal with. I will definitely be a returning customer.
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.
