RacingLine Stage 3 POWERMAX Software - Audi S3 8V

RacingLine Stage 3 POWERMAX software for Audi S3 8V. This is the turbo-upgrade calibration licence; the Garrett turbo and supporting hardware are purchased separately.

Gains: RacingLine publishes GPF-retaining POWERMAX graphs, but those are a different configuration from this listing. Exact gains for your non-GPF hardware and fuel must be confirmed before activation.

Choose your software package

• ECU only — £720.00 inc VAT (£600.00 ex VAT). Engine calibration licence.
• ECU + TCU — £1050.00 inc VAT (£875.00 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.

Full licence for new customers. If this vehicle already has an eligible OEM+ ECU licence, use the reduced-price POWERMAX upgrade instead. For DSG Stage 3, ECU only is suitable only when compatible TCU tuning is already present; otherwise select ECU + TCU where supported.

Stages and supporting hardware

RacingLine confirms Garrett POWERMAX GT2260S calibration support for non-GPF MQB EA888 Gen 3 applications. The turbo, intake, turbo inlet, intercooler, fuel-system requirements and exhaust configuration must be matched to the exact non-GPF calibration. Compatible DSG tuning is essential. Hardware is additional.

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

• Audi S3 8V — 2.0 TSI
• Engine/controller application: MQB 2.0TSI IS38
• Listed transmission: DQ250 / 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.
