Toyota Hiace 3.0 D-4D 170hp Remap

The Toyota Hiace 3.0 D-4D 170hp is a 3.0L turbocharged diesel engine producing 170 BHP and 360 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 210 BHP and 480 Nm — a gain of around 40 BHP (24%) and 120 Nm (33%).

This engine has moderate remap suitability, with gains weighted towards torque — you will notice the difference most strongly in mid-range pulling power and in-gear acceleration. The tuning headroom is classified as high, based on the percentage gain available from the factory output.

Considerations: High tuned torque: check transmission torque capacity and service history.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.. Older diesel: injector, turbo and intake condition can affect results; ensure maintenance is up to date.

Fuel economy note: economy gains unlikely at full power; depends on driving style.

All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
