Important: Power figures vary depending on fuel quality, tune stage, supporting hardware, ECU type, vehicle condition, transmission, and environmental conditions.
Mobile Flashing With IE POWERlink
IE POWERlink Mobile allows you to flash and manage your tune from your phone. Connect the POWERlink device to your vehicle’s OBD2 port, open the IE mobile app, and follow the guided flashing process.
- Flash your ECU from home
- No laptop required
- No ECU removal required
- Step-by-step flashing through the IE mobile app
- Access supported files within your purchased tune suite
- Read and clear fault codes
- Use live gauges and data logging
AutoProtect Engine Safety
IE’s AutoProtect system continuously monitors engine behaviour and can reduce power if unsafe operating conditions are detected. This helps maintain reliable performance while protecting the engine from poor fuel quality, knock, or abnormal running conditions.
The result is strong performance when conditions are right, with intelligent safety logic working in the background.
Adjustable Performance Features
Supported IE tune suites include adjustable features that can be changed directly through the POWERlink app without reflashing the ECU every time.
- Adjustable Exhaust Crackles: Turn crackles and burbles up, down, or off on supported files.
- Exhaust Flap Control: Control exhaust valve behaviour on supported vehicles.
- Adjustable Launch RPM: Fine-tune launch behaviour through the app or supported vehicle controls.
- Anti-Lag Launch Control: Builds boost before launching for stronger AWD acceleration on supported files.
- Rolling Anti-Lag: Helps preload boost while moving for faster response during rolling acceleration.
- Adjustable Throttle Response: Select from multiple throttle response settings, from smooth and linear to sharp and aggressive.
- Valet Mode: Limit vehicle performance when required on supported tune suites.
- No Lift Shift: Available for supported manual transmission vehicles.
- Boost By Gear: Helps optimise traction and boost delivery by gear on supported files.
TrueFlex Ethanol Support
With the required IE TrueFlex hardware, HPFP upgrade, and supported tune suite, the ECU can automatically read ethanol content and adjust boost, timing, and fueling in real time.
This allows you to run pump fuel, ethanol blends, or full E85 where supported without manually calculating mixtures or reflashing between fuel types.
Important: TrueFlex support requires compatible ECU software, IE TrueFlex hardware, required fueling upgrades, and the correct tune suite.
Recommended Upgrade Path
Stage 1 — Start Here
Stage 1 is the ideal starting point for stock or lightly modified Golf R and S3 vehicles. It delivers a noticeable power increase using the factory IS38 turbo and stock hardware. An upgraded intake is recommended for improved airflow and enhanced turbo sound.
For DSG-equipped vehicles, an IE DSG/TCU tune is strongly recommended to unlock full torque delivery, improve shift behaviour, and support higher-output ECU files.
Included with CORE, PRO & APEX
Stage 2 — Full IS38 Power
Stage 2 is designed to maximise the factory IS38 turbo. This setup generally requires an upgraded intake, intercooler, and downpipe. With the correct hardware, Stage 2 can deliver up to 461 HP with stronger acceleration across the entire powerband.
Included with PRO & APEX
GT2260S / Stage 3 — Go All Out
For maximum output, IE supports larger turbo setups such as the Garrett GT2260S with the correct Apex tune suite, HPFP upgrade, and supporting hardware. This setup can deliver up to 491 HP depending on fuel, hardware, and vehicle setup.
Included with APEX
Recommended Supporting Hardware
| Upgrade | Recommended For | Purpose |
|---|---|---|
| Intake System | All tune stages | Improves airflow and turbo sound |
| Turbo Inlet Pipe | All tune stages | Improves airflow into the turbocharger |
| Intercooler | Stage 2 and higher | Helps reduce intake air temperatures and maintain consistent performance |
| Downpipe | Stage 2 and higher | Improves exhaust flow and supports higher-output files |
| HPFP Upgrade | TrueFlex, ethanol, and Stage 3 setups | Supports increased fuel demand |
| GT2260S Turbo | Apex / Stage 3 builds | Supports maximum-output larger turbo performance |
| DSG / TCU Tune | DSG-equipped vehicles | Improves shift behaviour, clutch pressure, and torque handling |
