Navara NP300 — Stage 2 ECU Tune
- 69% increase in power output
- 38% increase in torque delivery
- Boost pressure increased to 35 psi (2.41 bar)
- Optimized EGT and fuel temperature parameters for safety
- Enhanced performance suitable for daily commute and towing applications
- Improved intercooling effectiveness through calibration
The NP300's 2.3-litre twin-turbo diesel responds well to boost and fuelling changes when you have proper control over both. This Stage 2 file targets wastegate solenoid duty, high-pressure fuel pump calibration, and injector mapping to lift output from 51 kW to 86 kW at the wheels, with torque climbing from 245 Nm to 338 Nm. Boost sits at 2.41 bar with EGT parameters dialled in to keep temps sensible under load.
The file assumes factory hardware with wastegate and fuelling tweaks already in place. Fuel temperature management and intercooling integration help keep things consistent during longer highway runs or when ambient temps climb. It's a solid outcome for a ute that sees regular towing or touring duty without chasing headline numbers.
Is this tune safe for daily driving and towing?
Yes. The calibration accounts for EGT management and fuel temperature to maintain reliability under load. Torque increase of 93 Nm is spread across the usable range, so it suits regular towing and highway work without stressing the drivetrain.
What hardware changes are required for this Stage 2 file?
The tune requires boost control modifications including wastegate solenoid optimization, along with high-pressure fuel pump and injector recalibration. Intercooling integration is also part of the package to handle the 2.41 bar boost level.
Can I run this on factory diesel, or does it need premium fuel?
Standard Australian diesel is fine. The tune is built around typical pump diesel quality and includes fuel temperature management to account for variations in fuel density during warmer months.
