iE IS38 Turbo Map Pack | Fits VW MK7 GTI, GLI, & Audi 8V A3 IESOVN17

Unlock the next level of performance with the Integrated Engineering (iE) IS38 Turbo Map Pack, designed for compatible 2015–2021 Volkswagen Golf GTI, 2019–2024 Volkswagen Jetta GLI, and 2015–2021 Audi A3 2.0T models. Developed specifically for vehicles upgraded to the larger IHI IS38 turbocharger, this calibration package helps unlock the turbo's performance potential while maintaining smooth power delivery and everyday drivability.

The IS38 turbocharger is larger than the factory IS20 unit commonly found on compatible GTI, GLI, and A3 applications. With increased airflow capacity, it provides the foundation for stronger acceleration and greater power potential when paired with the appropriate supporting hardware and engine calibration.

The iE IS38 Map Pack provides custom engine programming designed specifically for the IS38 turbocharger and integrates with the iE APEX Tune Suite. Developed and tested across different vehicles and operating conditions, the calibration is designed to deliver responsive power with predictable performance. Integrated AutoProtect safety logic monitors supported engine conditions and can reduce power when necessary to help protect the engine.

For enthusiasts seeking performance beyond a typical Stage 2 setup, the iE IS38 Map Pack provides a dedicated tuning solution for compatible MQB-platform vehicles. Proper hardware, fuel selection, and transmission calibration are essential to achieving the intended results.

Stage 3 Hardware Requirements

91 / 93 Octane Pump Gas

Required supporting components:

• Compatible air intake

• Upgraded intercooler

• Compatible downpipe

• IHI IS38 turbocharger

• Compatible transmission tune

• iE IS38 Map Pack

• iE APEX Tune Suite

TrueFlex E60–E70 Ethanol Blend

Required supporting components:

• Compatible air intake

• Upgraded intercooler

• Compatible downpipe

• IHI IS38 turbocharger

• Compatible TrueFlex kit

• High-pressure fuel pump (HPFP) upgrade

• Compatible transmission tune

Important: Confirm the required hardware, fuel specifications, and available calibration options for your exact vehicle before installation. Do not use an ethanol-blend calibration without the required fuel-system hardware and compatible TrueFlex configuration.

Activation & Installation

The iE Map Pack uses a digital delivery process tied to the serial number of a compatible POWERlink device.

• Locate the serial number beginning with V4 on the back of the POWERlink device.

• Enter the serial number during checkout as instructed by Integrated Engineering.

• Connect the POWERlink device to the compatible iE app through Bluetooth after purchase.

• Allow the system to synchronize the purchased credits through the cloud.

• The manufacturer states that credits should appear within approximately one hour, although processing times may vary.

• Follow iE's instructions to access and apply the appropriate calibration.

Note: Confirm that your POWERlink device, APEX Tune Suite, and existing software configuration support this specific Map Pack before ordering.

Fitment

2015–2021 Volkswagen Golf GTI — 2.0T, Front-Wheel Drive (FWD)

2019–2024 Volkswagen Jetta GLI — 2.0T, Front-Wheel Drive (FWD)

2015–2021 Audi A3 — 2.0T, All-Wheel Drive (AWD)

Important Tuning Compatibility & Disclaimers

• This Map Pack is intended for vehicles equipped with the compatible IHI IS38 turbocharger, not an otherwise stock IS20 configuration.

• Required intake, intercooler, downpipe, and transmission upgrades depend on the selected fuel and calibration.

• TrueFlex E60–E70 applications require the specified TrueFlex hardware and HPFP upgrade.

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

• Incorrect tuning or insufficient supporting hardware can affect engine reliability, drivability, and component life.

• Verify POWERlink compatibility, APEX Tune Suite requirements, and Map Pack activation eligibility before ordering.

• ECU and transmission tuning may affect emissions compliance and warranty coverage. Check applicable regulations before installation.
