RacingLine published engine-family reference, in PS and Nm. Factory output varies by vehicle. Figures are illustrative and depend on fuel, hardware, engine condition and test method.

Choose your software package

• ECU only — £720.00 inc VAT (£600.00 ex VAT). Engine calibration licence.
• ECU + TCU — £960.00 inc VAT (£800.00 ex VAT). Engine calibration plus tuning for the compatible gearbox controller.

Software price only. Flashing labour, fitting, PDM/cables, controller unlocks, turbochargers and other hardware are additional. Purchase the licence online; activation requires a compatible vehicle and installation arrangement. A software purchase does not include a PDM or an automatic download for an unsupported controller.

Stages and supporting hardware

Stage 1 needs no engine hardware changes. 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. Later locked controllers may need an unlock; that service is additional.

Calibration	Power (PS)	Torque (Nm)
Stage 1, lower torque	345	480
Stage 1+ with TCU	367	539
Stage 2 with TCU, non-GPF	389	559

Stage 3 POWERMAX is available with a separate licence price. View this vehicle’s POWERMAX software. The Garrett POWERMAX calibration is distinct from the RacingLine hybrid-turbo Stage 3 route.

Why RacingLine OEM+?

RacingLine develops its calibrations alongside its performance hardware, with experience from road, track and dyno testing. 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.

Compatible 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. A gearbox licence does not include a physical clutch or a controller unlock.

Vehicle compatibility and installation

• Cupra Leon Mk4 — 2.0 TSI 245
• Engine/controller application: 2.0TSI GEN4 GARRETT
• Listed transmission: DQ381

Match the engine code, original power, turbo, emissions equipment and ECU/TCU software IDs before activation. A registration year alone does not establish compatibility. Newer locked controllers may require an additional unlock or may not support direct flashing.

Installation is through an authorised tuning centre or, for a supported application, a separately purchased RacingLine PDM. PDM availability must be checked for the actual controller; it is not included in this listing.

Tuning can affect manufacturer warranty and insurance cover. Retain emissions equipment required for road use, and maintain the vehicle appropriately for the increased output.
