BEFORE TUNING
Before remapping your BMW M760Li xDrive, we recommend checking that your vehicle is in good mechanical condition. Any existing engine warning lights, fault codes or running issues should be diagnosed before tuning.
Our team can discuss your vehicle’s condition, intended performance goals and suitability for remapping before work begins. Given the V12 engine’s complexity and high torque output, the turbocharging system, cooling system, ignition components and drivetrain should be carefully assessed before increasing performance.
SERVICING AND MAINTENANCE
Regular servicing is essential for maintaining performance and reliability. We recommend following BMW’s maintenance schedule and ensuring the engine oil, filters, spark plugs, ignition components and cooling system are in suitable condition before tuning.
High-performance vehicles may require more frequent maintenance depending on driving style and usage. Correct servicing helps support consistent performance and long-term engine health.

An upgraded exhaust system can complement your BMW M760Li xDrive’s performance upgrades and enhance its V12 sound and character. Depending on your requirements, available options may include suitable performance exhaust systems and related components.
