Toyota HiLux Diesel Tuning & Servicing
The Toyota HiLux is the workhorse of Australia, but the diesel under the bonnet has changed a great deal across the generations. Current GUN-series utes run the 2.8-litre 1GD-FTV (first 130kW, later uprated to 150kW and 500Nm on the auto) or the smaller 2.4-litre 2GD-FTV producing 110kW and 400Nm. Both are common-rail, variable-nozzle-turbo, DOHC engines fitted with a diesel particulate filter (DPF), EGR and tight factory emissions calibrations that leave real, usable performance on the table. At Willy’s Workshop we tune these in-house on our own dyno, working with the factory Denso ECU rather than piggy-backing it.
Plenty of HiLux owners are still running the previous KUN-series trucks, and we look after those too. The 3.0-litre 1KD-FTV (KUN26, 2006-2015) and the 2.5-litre 2KD-FTV (KUN16, 2005-2015) are proven D-4D engines, while earlier 1KZ-TE and 5L-E 3.0-litre HiLuxes still turn up regularly. Each generation has its own quirks: the 1GD/2GD are defined by the DPF and airbox-dusting saga, while the 3.0L 1KD-FTV is best known for injector and carbon issues. We tailor every tune and service to the specific engine and platform in front of us.
Premium diesel performance and honest mechanical repair sit side by side at Willy’s Workshop. Whether you want a dyno-verified power and economy gain for towing and touring, or you need a dusted MAF sensor, leaking injectors or a clogged DPF sorted properly, our Oxley (Brisbane) and Warana (Sunshine Coast) workshops cover both ends of QLD. Every job is matched to how you actually use your HiLux.

Toyota HiLux diesel engines we tune
Your HiLux's tune potential
Pick your engine to see typical gains from a Willys Workshop tune.
Indicative gains on a stock vehicle, measured on a dyno at the engine (crank) — wheel power reads lower (typically 15–20% on a 4WD). Actual results vary with vehicle condition, fuel quality and modifications.
Indicative rear-wheel (dyno) figures with switchable maps, emissions intact. Actual results vary with vehicle condition, fuel quality and modifications.
Why choose Willy’s for your Toyota HiLux
Performance Tuning
Custom, dyno-verified ECU tuning developed in-house on the factory Denso ECU for every HiLux diesel generation.
- Custom in-house tuning of the factory Denso ECU on the 1GD-FTV 2.8L and 2GD-FTV 2.4L, plus the older 3.0L 1KD-FTV and 2.5L 2KD-FTV D-4D engines.
- Dyno-verified before-and-after results, with each calibration developed on the car rather than loaded from a generic file.
- Tuning targeted at real-world towing, touring and daily driving, with sharper throttle response, improved mid-range torque and better drivability under load.
- Calibration work matched to supporting hardware such as intakes, exhausts and intercoolers so the engine is optimised as a complete package.
Servicing & Repair
Full diesel servicing and repair for every HiLux generation, from routine logbook work to the platform’s well-known faults.
- DPF and EGR diagnosis, cleaning and repair on 1GD-FTV and 2GD-FTV HiLuxes, including the carbon and soot build-up these engines are prone to.
- Airbox and MAF sensor service for the GD-series dusting issue, where dust past the air filter corrupts the mass air-flow sensor and triggers limp mode.
- Injector testing and replacement on the 3.0L 1KD-FTV, addressing the rough idle, cold knock, white smoke and copper-washer faults these engines are known for.
- Routine logbook servicing, timing, cooling, turbo and driveline work across 1KD, 2KD, 1KZ-TE and 5L-E HiLuxes at both Oxley and Warana.
