This month, we’re focusing on the 2025 BMW G99 Touring — a vehicle that embodies everything great about BMW: luxury, practicality, and driving dynamics. As a premium estate, the G99 Touring blends comfort and capability with the kind of performance pedigree you expect from the Bavarian brand. But with the addition of a TDI Tuning-enhanced, traceless, plug-and-play system, the G99 Touring is transformed into something even more special.
Tuning Potential
The 2025 BMW G99 Touring is only available with one petrol hybrid engine, which delivers a strong balance of performance and efficiency. From long-distance driving to short spirited cruises, the Touring is designed to adapt to a variety of driving needs.
However, like most modern vehicles, BMW’s powertrains are restricted by factory software that prioritises global compliance and generalised performance rather than the full potential of each engine. This means there’s hidden performance locked away, waiting to be unleashed.
Our CRTD4 offers boosted power overall plus increased torque, which transforms the towing ability, low-end power increasing with the rev range and low-speed drivability. The G99 also benefits from improved efficiency, reducing running costs, especially for high-mileage drivers. All without compromising the reliability, manufacturer's warranties or safety of the G99.
What We Offer
TDI Tuning specialises in traceless, plug-and-play tuning systems that enhance a vehicle’s performance without permanently altering its ECU. Unlike remapping, which overwrites the factory software and leaves behind a digital footprint, our system installs in under an hour, can be removed at any time, and leaves no trace of modification.
This is a huge benefit for owners of a brand-new 2025 BMW G99 Touring, many of whom purchase through finance or lease agreements. With our system, you can enjoy all the advantages of tuning without risking warranty issues or affecting residual value.
Our technology integrates seamlessly with BMW’s advanced engine management. The tuning box communicates with the ECU in real time, optimising fuel and boost signals to safely increase power and efficiency. For drivers who want flexibility, our optional Bluetooth app control allows tuning settings to be adjusted instantly from a smartphone.
This means the G99 Touring goes from 717 BHP & 1000 NM to a staggering 839 BHP & 1240 NM! These are serious power and torque increases over stock, which will make going through the rev range even smoother with faster power delivery and a noticeable boost in low-end torque, which will maintain under heavy load and as you increase in speed.
Performance Gains
The results of a TDI Tuning system on the G99 Touring are both measurable and noticeable. Depending on the engine variant, owners can expect:
- Horsepower increases, delivering stronger acceleration and greater responsiveness.
- Torque gains, ideal for towing, overtaking, and low-speed drivability.
- Fuel savings of up to 20%, especially on long motorway journeys where efficiency matters most.
- Sharper throttle response, giving the Touring a sportier, more agile character.
This tuning box unlocks smoother, more powerful delivery across the rev range, making spirited driving more enjoyable. The added torque makes light work of towing and high-mileage cruising. Our system enhances the hybrid-petrol engine’s contribution, creating a seamless blend with the electric motor and improving overall performance.
In every case, the transformation is immediate. The G99 Touring feels more alive, more confident, and more versatile, without losing the refinement and comfort that make it such a desirable car.
Additional Benefits
Our traceless installation provides peace of mind, especially for those with cars under finance or warranty. The system can be removed in minutes, restoring the car to its factory state with no evidence of modification.
The Bluetooth control app adds another layer of convenience, allowing drivers to tailor their car’s performance to suit the moment. Heading on a long motorway run? Switch to economy mode for better fuel savings. Tackling twisty roads on the weekend? Switch back to maximum performance for a sharper response.
Conclusion
The 2025 BMW G99 Touring is already a standout car: stylish, practical, and engineered for drivers who want both versatility and excitement. But with a TDI Tuning enhanced plug-and-play system, it evolves into something even greater.
By unlocking hidden horsepower and torque, improving efficiency, and giving you real-time control over your car’s performance, our tuning system makes the G99 Touring sharper, more capable, and more enjoyable to drive.
