For DSG-equipped vehicles, the matching IE DSG Tune is recommended to support increased engine torque, enable the applicable 7,000 RPM limit, and improve transmission performance.

Stage 2 – Bolt-On Performance Tune

The IE Stage 2 ECU Tune is designed for vehicles equipped with supporting intake, intercooler, and downpipe upgrades. These modifications increase airflow and improve charge-air cooling, allowing the calibration to take advantage of the factory turbocharger's performance potential.

With the required supporting hardware, Integrated Engineering advertises output of up to 394 horsepower for the applicable Stage 2 configuration.

Stage 2 Required Hardware:

• Compatible performance intake.

• Upgraded intercooler.

• Compatible performance downpipe.

• IE Pro or Apex tuning package, as required by the selected calibration.

A compatible cat-back exhaust can complement the setup and support the use of available exhaust sound features.

Stage 3 – Upgraded Turbocharger Performance

For enthusiasts seeking performance beyond the factory IS20 turbocharger, Integrated Engineering offers higher-stage tuning options designed for compatible upgraded turbocharger configurations.

IS38 Turbocharger Configuration

Upgrading to the factory Golf R IS38 turbocharger with the appropriate IE Map Pack provides an advertised output of up to 409 horsepower for the applicable setup.

Garrett GT2260S Turbocharger Configuration

For greater top-end performance, the Garrett GT2260S turbocharger paired with the required high-pressure fuel pump upgrade and Stage 3 Map Pack delivers advertised output of up to 462 horsepower.

Stage 3 Supporting Hardware:

• Compatible upgraded turbocharger.

• Required IE Map Pack for the selected turbocharger.

• High-pressure fuel pump upgrade for the specified GT2260S configuration.

• Supporting intake, intercooler, fueling, and exhaust components as required by the selected setup.

Important: Stage 3 hardware and software requirements vary by turbocharger configuration. Confirm the exact IE application and required supporting components before ordering.

Advanced Performance Features

Adjustable Throttle Response

Compatible IE calibrations provide proportional throttle response mapping, with up to 15 customizable settings ranging from smooth and progressive to sharp and aggressive.

Available settings can be adjusted through the supported mobile application, allowing drivers to tailor throttle response to different driving conditions.

Exhaust Crackles

Supported calibrations offer adjustable exhaust crackle and burble functionality. Drivers can enable, reduce, or disable the feature through the app where supported.

Exhaust sound results depend on the installed exhaust system, calibration, and vehicle configuration.

Anti-Lag™ Launch Control

IE Anti-Lag™ Launch Control is designed to build engine RPM and turbocharger boost before launch, helping reduce turbo lag during acceleration.

Available launch settings can be adjusted through supported application controls or compatible cruise-control stalk functions, depending on the vehicle and software.

Rolling Anti-Lag™ (RAL)

Compatible Rolling Anti-Lag™ functionality helps prepare the turbocharger for acceleration while the vehicle is moving. Availability depends on the selected calibration, hardware, and vehicle configuration.

TrueFlex™ Ethanol Tuning

The IE TrueFlex™ system is designed to monitor ethanol content and adjust supported engine parameters according to the fuel mixture in the tank.

With the required compatible flex-fuel hardware and software, supported vehicles can use pump gasoline, E85, or intermediate ethanol blends without manually measuring the mixture for every fill-up.

Important: TrueFlex™ requires the appropriate compatible hardware and calibration. It should not be assumed to be included or supported on every vehicle or tune package.

Engine Protection Technology

IE calibrations incorporate engine protection strategies designed to monitor operating conditions and adjust power when necessary. AutoProtect™ functionality is available where supported by the specific tuning application.

These safeguards do not eliminate the need for correct fuel, proper installation, regular maintenance, and compatible supporting hardware.
