The most advanced turbodiesel water-methanol injection system on the market — the only kit proven to improve fuel economy and reduce emissions across all load ranges. The Stage 3 TD MPG-MAX uses 2D mapping based on boost pressure and exhaust gas temperature (EGT). Successfully tested by the U.S. Department of Energy at the National Renewable Energy Laboratory.

What's in the Box

• 300 PSI EPDM high-pressure pump (100% methanol-resistant, double-sealed)
• Stage 3 TD MPG-MAX controller with LCD display — 2D mapping via boost + exhaust gas temperature
• EGT probe (exhaust gas temperature sensor) — included in kit
• 2× Hyper-Sonic™ injection nozzles (economy + power nozzle) with integrated 100-micron filters
• Dual Stage Technology (DST) included — economy nozzle for cruise, power nozzle for full load
• 3-litre reservoir (black) with pump mount
• Fluid level switch with LED warning light (red)
• OEM-grade weather-tight wiring harness (terminated connectors)
• All fittings, pressure lines, and mounting hardware
• Comprehensive installation manual

Key Features

• Injection type: Variable 2D-mapped (boost pressure × exhaust gas temperature)
• Fuel economy mode: Small nozzle injects a fine mist across the entire power curve — improves combustion efficiency for 5–15% fuel savings
• Power mode (DST): Secondary power nozzle activates at adjustable load point for maximum performance under heavy throttle
• Display: LCD shows boost pressure (BAR/PSI), EGT (°C/°F), and injection volume (%)
• Emissions: Significantly reduces NOx emissions — US DOE/NREL testing confirmed
• Engine compatibility: All turbodiesel engines — especially suited for towing vehicles, trucks, and marine

How It Differs from Other Stages

The MPG-MAX is the only diesel kit with EGT-based 2D mapping — it knows exactly how hot your engine is running and adjusts injection accordingly. Stage 2 TD only reads boost pressure. The MPG-MAX also uniquely targets fuel economy across all load ranges, not just power under boost.
