Factory gearbox software prioritises comfort and fuel economy over performance. Our TCU calibration reduces shift lag, holds gears longer during spirited driving, improves kick-down response and optimises launch control on DSG-equipped vehicles. The result is a cohesive, responsive drivetrain that matches your engine remap.
For vehicles with automatic, DSG or S-Tronic transmissions, a TCU (Transmission Control Unit) remap transforms the driving experience. We fine-tune shift speeds, shift points, launch control and hydraulic pressure to complement your engine's power delivery, essential when paired with Stage 1 or Stage 2 ECU remaps.

Frequently Asked Questions
