“Our RacingLine Performance Software is simply the most effective modification you can make to a modern turbocharged engine. We don’t just overwrite the existing software – we take the manufacturer’s philosophy and create a completely new calibration designed from scratch exclusively for each model.” - RacingLine Performance

OEM+ is RacingLine’s factory styled calibration suite for VAG platforms. Rather than crudely overwriting stock maps with untested software, each file is built from the ground‑up for a specific engine and ECU. Each software calibration has been extensively tested on the dyno, track and road meaning there is no risk of bad software being written to your car's ECU.

Key benefits

• Beautiful driveability: strong, consistent torque with smooth pedal mapping and thermal protection.

• ‘True Stock’ option: revert the ECU to its exact pre‑tune state if needed (e.g., dealer visits).

• Free stage 2 software upgrades: start on Stage 1 and move to higher stages at no extra software cost when you add the supporting hardware required.

• TCU ‘Dynamic’ DSG software: faster shifts, smarter torque management, and raised limits to suit the ECU tune.

• OEM grade development philosophy: Each calibration is built using OEM level calibration techniques for the perfect balance of performance, efficiency, and reliability.

• Hardware matched tuning: Every tune is designed to work in harmony with RacingLine Performance Parts for seamless integration between software and hardware.

(Exact hardware varies by engine and vehicle-ask our team for a build plan.)

• Stage 1 (Road/Stock hardware): High impact ECU remap on a healthy, serviced car. Optional TCU tune recommended on DSG/S-tronic.

• Stage 1+ (Where applicable): ECU + intake/intercooler or high‑flow panel/cooler packages for sustained performance.

• Stage 2 (Hardware matched): Downpipe/OPF‑safe options where available, intercooler, intake, and supporting cooling. TCU tune essential on DSG.

• Stage 3 (Platform dependent): Turbo upgrades with full hardware and exhaust system consideration.

We’ll always confirm the right stage, list required parts, and provide a written quote before suggesting work needed.

• EA888 Gen 3 / Gen 4 2.0 TSI – Golf GTI/R (Mk7–8), S3 8V/8Y, TTS/TT, Cupra Leon/Formentor/Ateca, Arteon/Tiguan R, and more.

• 2.5 TFSI (DAZA/DNWA) – RS3 8V/8Y, TTRS, RSQ3.

• 3.0 TFSI – Selected V6 models.

• VAG TDI – Selected diesel applications.

If you don’t see your car listed, just ask, we’ll check coverage and options for your exact engine/ECU code.

We do offer tuning on other marques of vehicles including BMW, Mercedes and Ford, but for our VAG customers our OEM+ software is the best on the market.  

1. Pre tuning health check (fault scan, fluid check, visual inspection).

2. Baseline (optional dyno power run where applicable).

3. OEM+ ECU install via OBD or bench as per ECU type.

4. Optional TCU (DSG) software to match torque delivery and shift strategy.

5. Road test / data check and customer handover.

6. Aftercare: map revision support, hardware upgrade pathway, and future stage upgrades.

Or send us your registration, engine code (if known), and current mods, we’ll come back with a recommended stage, parts list, and a fixed-price proposal.

Helpful things to check prior to your visit for best results
