BEFORE TUNING
Before remapping your BMW X5 M F85, we recommend a comprehensive vehicle health check. The S63 V8 engine, turbochargers, ignition system, cooling system, fuel system and drivetrain should be in good condition before increasing performance.
Any existing fault codes or mechanical issues should be investigated before tuning begins. Ensuring the vehicle is correctly maintained is particularly important when increasing the output of a high-performance twin-turbocharged engine.

Regular maintenance is essential for preserving the reliability and performance of your BMW X5 M. We recommend following the appropriate servicing schedule and using quality engine oil, filters, spark plugs and other components suitable for the S63 V8 engine.
Vehicles operating at increased power levels may benefit from more frequent servicing, depending on driving style and usage.

An exhaust upgrade can complement your BMW X5 M remap by enhancing exhaust flow and the V8 soundtrack. Available options may include performance exhaust systems, compatible downpipes and other exhaust components suited to your performance goals.
All modifications should comply with applicable road-use, emissions and noise regulations.
