Unlock safe, proven gains with professional ECU tuning for a more responsive Isuzu D-Max 2.5 TD (2003–2012) with our in-house ECU calibration. Whether you choose a Stage 1, 2 or 3 calibration, each level is designed to safely enhance performance, torque, and drivability for your exact setup. Tuning is completed in-house by Sunshine Coast Diesel Tuning using advanced, licensed calibration tools with dyno verification available.
Stage 1 – The Best Bang for Your Buck
Stage 1 tuning delivers the most noticeable improvement for the least cost — a true transformation without changing any factory hardware. Power increases from 136 hp → 175 hp and torque from 294 Nm → 370 Nm, resulting in smoother delivery, stronger mid-range pull, and improved towing performance.
Measured Gains: +39 hp / +76 Nm (136 hp → 175 hp, 294 Nm → 370 Nm)
Hardware: No modifications required
Benefits: Sharper throttle, smoother drivability, safer overtaking power
Recommended Upgrades: Intercooler, performance intake, and cat-back exhaust to enhance cooling and airflow
Stage 1 is the biggest bang-for-your-buck upgrade — reliable, efficient, and ideal for daily driving or towing applications.
Stage 2 – Performance Hardware Upgrade
Stage 2 tuning is designed for D-Max owners looking to take performance further with key supporting hardware upgrades. This calibration builds on Stage 1 but delivers higher torque and stronger power under sustained load. It’s perfect for heavy towing, touring setups, or off-road builds that demand more pulling power and efficiency.
Expected Gains: +55 hp / +100 Nm (approx. 190 hp / 394 Nm total)
Minimum Requirements: Upgraded intake, full turbo-back exhaust, and front-mount intercooler
Benefits: Increased mid-range torque, reduced EGTs, and improved response at low RPM
Custom Calibration: Individually adjusted mapping for each hardware configuration
Stage 2 tuning transforms drivability under load, delivering confident towing performance and consistent power in demanding Australian conditions.
Stage 3 – Maximum Performance
Stage 3 tuning pushes the Isuzu D-Max 2.5 TD to its performance limits, engineered for vehicles with full supporting upgrades including turbocharger, fuel system, and cooling modifications. Designed for high-performance, competition, or dedicated off-road builds, this tune offers substantial gains while maintaining reliability through precise calibration.
Expected Gains: +80 hp / +140 Nm (approx. 215 hp / 434 Nm total)
Minimum Requirements: All Stage 2 hardware plus upgraded fuel system and turbocharger
Purpose: Maximum output for performance and off-road applications
Custom Tuning: Tailored calibration ensuring safe operation under extreme load and temperature conditions
For serious enthusiasts and performance builds, Stage 3 delivers unmatched power, torque, and throttle response.
