Stage 1+ requires the R600 intake pack, turbo inlet and intercooler and retains the factory GPF. Stage 2 additionally requires the specified high-flow catalyst and is unsuitable for UK road use where it requires GPF removal. High-torque figures require compatible TCU tuning; lower-torque calibrations are available when TCU tuning is unavailable or for a manual gearbox.

The aim is a consistent delivery of power and torque with smooth everyday behaviour, rather than a peak figure alone. OEM+ also supports a return to the vehicle’s original stock calibration.\u003c\/p\u003e\u003cp\u003eCompatible gearbox tuning revises torque handling and shift behaviour to complement the ECU calibration. DSG dynamic software varies clutch pressure with load, combining everyday driving with the extra torque of the engine calibration.
