Gearbox / TCU Tuning
Faster shifts. Higher torque limits.
Your gearbox has a computer too — and it's just as capped as the engine ECU. A TCU (Transmission Control Unit) calibration rewrites shift maps, torque limits, clutch pressures and — on many platforms — unlocks launch control that was disabled by the factory. The result is a car that shifts like it was engineered to a much higher spec.
Which gearboxes do you tune?
VW/Audi DSG (DQ200 7-speed, DQ250 6-speed, DQ381/500 7-speed), Porsche PDK, BMW DCT (M2/M3/M4), ZF 6HP and 8HP (BMW, Range Rover, Jaguar), Mercedes 7G-Tronic and 9G-Tronic, Ford Powershift. Others by request.
Why tune the gearbox as well as the engine?
Because factory gearbox torque limits are often the true bottleneck. A Stage 2 engine map can make more torque than a stock TCU will allow the box to deliver — the gearbox will clutch-slip or de-torque under load. A matched TCU calibration lets you use every last Nm.
Is a TCU remap safe?
Yes when calibrated correctly. We stay within the mechanical hardware limits of your specific gearbox — that's why we won't do a Stage 3 TCU on a stock DQ250 with a poverty-spec clutch pack. We tell you honestly what your box can and can't handle.

Not when written within the mechanical limits of your specific box and clutch pack. We calibrate conservatively for daily-driven cars.
Yes — factory launch control is available with our DSG map and is fully refined for street use.
Yes — the ZF 8HP responds beautifully to a proper TCU calibration; a favourite platform of ours.
