Mercedes X-Class 220d ECU Tune

Unlock safe, proven gains with professional ECU tuning for a more responsive Mercedes X-Class 220d (2017-on) 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 163 hp to 190 hp and torque from 403 Nm to 460 Nm, resulting in smoother delivery, stronger mid-range pull, and improved towing performance.

• Measured Gains: +27 hp / +57 Nm (163 → 190 hp, 403 → 460 Nm)
• Hardware: No modifications required
• Benefits: Sharper throttle, smoother drivability, safer overtaking power
• Recommended Upgrades: While not required, an intercooler, performance intake, and cat-back exhaust can enhance cooling and airflow, unlocking even better performance.

The Mercedes X-Class 220d ECU Tune 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 builds on the Stage 1 calibration but is designed for vehicles fitted with key supporting modifications. This level delivers higher torque and sustained power under load, making it ideal for heavy towing, off-road setups, or performance-oriented builds.

• Minimum Requirements: Full exhaust system, upgraded intake, and improved intercooler/cooling system
• Benefits: Increased torque and mid-range response, reduced EGTs, and more efficient airflow for prolonged high-load performance
• Custom Calibration: Each tune is individually adjusted to suit your hardware setup for optimal balance between power and reliability

Stage 3 – Maximum Performance

Stage 3 tuning is designed for full performance builds where every supporting system has been upgraded. It provides significant gains in both power and torque through advanced fuelling and charge system improvements.

• Minimum Requirements: All Stage 2 upgrades plus fuel system modifications and a turbocharger or supercharger upgrade
• Purpose: Built for high-performance or competition/off-road use where power delivery and responsiveness are prioritized over comfort
• Custom Tuning: Tailored calibration for each build to ensure safe operation under extreme conditions
