What makes Pro+Boost stand out

• Dual channel control manages common-rail fuelling and turbo boost together for balanced, repeatable performance
• Boost Sense and Rev Sense technology for precise on-boost and off-boost fuelling; smokeless and particulate-filter friendly
• Five selectable driving modes so you can choose economy, fast-road punch or a strong tow-friendly setup
• Noticeably meatier torque through the middle revs for confident overtakes and relaxed motorway cruising
• Sharpened pedal response and reduced lag for a more immediate, engaging drive
• Weather-sealed aluminium housing designed for under-bonnet durability
• Non-invasive install that is traceless once removed and warranty sympathetic
• Re-programmable hardware you can carry over to future vehicles
• DPF, ECU and EGR safe with clean combustion and controlled exhaust gas temperatures

Real-world performance you can feel

Blackbox mapping is developed to build torque early and hold it across the rev range. That means faster roll-on acceleration, fewer downshifts and effortless pace where you use it most. Your 325d feels stronger everywhere, not just at peak power.

Clean, reliable and DPF-safe

Many generic modules overfuel off boost which creates haze and DPF issues. Pro+Boost uses Boost Sense with Rev Sense to transition fuelling accurately, keeping AFRs consistent and EGTs in check. Ideal for daily driving and towing while protecting components.

Economy benefits

Driven sensibly, diesel owners commonly see around a 10 percent improvement in MPG thanks to the extra torque. Use the added performance frequently and the economy gain will be smaller.

Fast, reversible installation

Supplied with clear photographic instructions, the Pro+Boost plugs in with no cutting or coding and can be removed in minutes.
