RaceChip GTS Black Tuning Boxes at JXL Performance

When modern performance vehicles leave the factory, their engine control units (ECUs) are locked down with complex security measures that prevent traditional remapping. For owners who want to dramatically increase power without cracking open or permanently modifying their factory ECU, RaceChip provides the ultimate plug and play tuning solution. As a world leader in auxiliary tuning box technology, RaceChip engineers the GTS Black series to deliver massive horsepower and torque gains safely, seamlessly, and with the complete ability to return the car to stock at a moment's notice.

Plug and Play Power Without ECU Tampering

Traditional ECU remapping requires bench unlocking or modifying factory software, which can often be flagged by dealership diagnostic tools during routine servicing. RaceChip completely bypasses this limitation by utilizing a sophisticated, high performance microprocessor tuning box that connects directly to your engine's critical electronic sensors.

The GTS Black intercepts and optimizes real time signals, such as boost pressure, manifold pressure, and rail pressure, allowing the engine to produce significantly more power while keeping factory engine safety protections fully active. Furthermore, the unit features fine tuning app control, allowing you to seamlessly switch between efficiency, sport, and race maps directly from your smartphone.

Factory Locked BMW and Audi Platforms

RaceChip GTS Black tuning boxes are exceptionally popular for modern vehicles featuring factory ECU locks that cannot be easily remapped. In the BMW tuning scene, they provide an incredible, warranty friendly power increase for newer locked ECU models, including the B58 powered M140i, M240i, M340i, and the twin turbo S58 engines in the G80 M3 and G82 M4.

They are equally dominant in the high end VAG market, making it easy to unlock massive performance gains on heavily secured platforms like the Audi S3, RS3, and the twin turbo V8 RS6 without risking a permanent software flag.
