What Is DSG / TCU Tuning?

DSG and TCU tuning adjusts the software that controls your automatic or dual-clutch gearbox. The TCU, or Transmission Control Unit, manages how and when your gearbox changes gear.

A TCU tune can improve:

Shift speed
Gear change response
Torque limits
Launch control behaviour where supported
Driveability
Gear holding
Throttle and gearbox communication
Performance after engine remapping

Why Tune Your Gearbox?

When a vehicle is remapped, the engine may produce more torque than the gearbox software is originally set up to handle. In some vehicles, the gearbox software can limit performance even after an engine remap.

A DSG or TCU tune helps the gearbox work better with the engine, improving the overall driving experience.
