Why Your D12 Deserves Better Than Stock Performance
Your Volvo D12 is engineered for excellence, but it ships from the factory with conservative settings designed to meet regulatory requirements—not to maximize YOUR profitability. That means you're operating at a fraction of your engine's true capability, leaving money on the table with every mile.
Our tuning solutions change that.
Two Proven Tuning Solutions for Your D12
We offer two professional tuning options engineered specifically for 1997-2007 Volvo D12 engines:

A removable performance module that connects to your engine harness and sensors. Installs in minutes, fully reversible, and transferable between vehicles.
Perfect for operators who value flexibility and want to maintain factory ECU integrity.
Option 2: ECU Re-Flash Tuning - 1997 - 2007
A permanent software modification to your engine's computer that optimizes performance parameters at the source. Delivers maximum performance gains with seamless integration.
Ideal for operators seeking ultimate power, efficiency, and a long-term commitment to a specific vehicle.
Both solutions deliver:
- Substantial fuel economy improvements (5-15%+)
- Significant power and torque gains (40-100+ hp, up to 350 lb-ft torque)
- Proven reliability and durability
