iE Stage 3 Turbo Map Pack | Fits Audi B9 A4

Unlock big-turbo performance with the Integrated Engineering (iE) Stage 3 Turbo Map Pack, designed for compatible Audi B9 A4 2.0T applications equipped with the Turbo Systems Hybrid turbocharger. Developed specifically for this upgraded turbocharger configuration, the Stage 3 calibration is engineered to deliver up to 424 horsepower, combining strong acceleration, sustained top-end power, and smooth, predictable drivability.

Unlike generic big-turbo tunes, the iE Stage 3 Map Pack uses custom engine programming calibrated for the Turbo Systems Hybrid turbocharger. This application-specific approach is designed to optimize power delivery throughout the rev range while maintaining responsive acceleration and everyday usability.

The calibration incorporates AutoProtect safety logic, which monitors supported engine operating conditions and can reduce power when necessary to help protect the engine. Although the setup is designed to deliver high performance with compatible factory engine internals, actual reliability depends on engine condition, installation quality, fuel, and supporting hardware.

The iE Stage 3 Turbo Map Pack integrates with the iE APEX Tune Suite and compatible POWERlink hardware. The specified configuration requires supporting intake, intercooler, downpipe, fuel-system, sensor, and injector upgrades to accommodate the demands of the hybrid turbocharger.

Manufactured by Integrated Engineering, this Map Pack is designed for Audi enthusiasts looking to move beyond the factory turbocharger and build a performance-focused B9 A4 with a dedicated hybrid-turbo calibration.

Important Tuning Compatibility & Disclaimers

• This Map Pack is specifically intended for compatible Turbo Systems Hybrid turbocharger applications.

• The required intake, intercooler, downpipe, HPFP, MAP sensors, and injectors must be compatible with the selected calibration.

• The manufacturer lists a Stage 3 transmission tune as part of the required configuration; verify compatibility with your transmission and whether it must be purchased separately.

• Use only the calibration developed for your exact vehicle, hardware configuration, and fuel type.

• AutoProtect is designed to help manage certain engine risks but cannot eliminate all mechanical risks or guarantee engine longevity.

• ECU and transmission tuning may affect engine reliability, component life, emissions compliance, and warranty coverage. Check applicable regulations before installation.
