Toyota LandCruiser Prado Diesel Tuning & Servicing
The LandCruiser Prado is one of the most common touring 4WDs on Queensland tracks, and at Willys Workshop we see them daily across both our Oxley and Warana sites. The platform spans several diesel generations: the 1KD-FTV 3.0-litre fitted to the 120 Series and early 150 Series, the 1GD-FTV 2.8-litre that took over with the facelifted 150 Series from 2015, and the latest 250 Series (from 2024) running an updated 1GD-FTV 2.8 producing 150kW and 500Nm, paired to an eight-speed automatic and offered with Toyota’s 48V V-Active mild-hybrid assist. Each engine has its own character, its own weak points, and its own response to a properly developed tune.
These engines are built to tow and to cover distance — the 250 Series carries a 3500kg braked rating — but the factory calibration is set conservatively for global emissions targets, not for a fully loaded touring rig climbing the Range in 38-degree heat. Where Prados commonly come unstuck is the diesel particulate filter (DPF), which clogs on short-trip town driving and was the subject of a Federal Court class action against Toyota over earlier 2.8 models; the airbox dusting issue on 2.8 models that lets fine dust foul the airflow sensor and drop the engine into limp mode; EGR carbon build-up choking the intake; and on the older 1KD, injector and piston wear that needs to be caught early.
Our tuning is custom, developed in-house on the factory ECU and verified on the dyno — never a generic file flashed and sent on its way. We tune for how you actually use the vehicle, whether that’s towing a van up the Bruce Highway or running corrugations to Cape York, with a focus on usable low-down torque, cleaner throttle response and sensible exhaust gas temperatures under load.

Your Prado'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 Prado
Performance Tuning
Custom, dyno-verified tuning developed on the factory ECU for how you actually drive your Prado.
- Custom in-house ECU calibration on the 1GD-FTV 2.8 and 1KD-FTV 3.0, developed and dyno-verified on our equipment — not an off-the-shelf file
- Tuned for towing and touring: stronger, smoother low-down torque where it matters when loaded, with throttle response sharpened for stop-start and trail driving
- EGT (exhaust gas temperature) monitoring built into the development process so the tune stays safe under sustained load on long climbs
- Calibration matched to supporting modifications — intake, exhaust, intercooling and transmission behaviour — so the whole package works together rather than fighting itself
Servicing & Repair
Full diesel servicing and repair targeting the faults Prados are genuinely known for.
- DPF diagnosis, forced regeneration and cleaning — the common failure point on town-driven 2.8 Prados — plus advice on driving patterns that keep it healthy
- EGR system inspection and carbon decontamination of the intake manifold and valve to restore airflow on higher-kilometre engines
- Airbox and airflow sensor checks to address the known dusting issue that throws 2.8 models into limp mode
- Injector testing, turbo health checks and scheduled diesel servicing — critical for catching 1KD injector and piston wear before it becomes a major bill
