Unlock stronger acceleration, sharper throttle response and serious mid‑range pull with the RaceChip GTS Black power module featuring Bluetooth smartphone control. This premium piggyback ECU solution is a brilliant remap alternative for the BMW X3 F25, giving you impressive gains without permanent changes to the factory software.

Why enthusiasts choose this upgrade

• Up to 30% more power and torque within safe reserves — ideal for faster overtakes and effortless cruising
