IE's record breaking software brings track-ready ECU programming to your Audi Volkswagen 2.0T IS20 MQB such as MK7/MK7.5 Golf GTI/GLI & 8V/8V.5 A3, while retaining factory comfort and reliability. Developed in-house, IE engineers are equipped with industry-leading tuning technology to completely reverse engineer the factory mapping and safely modify it to maximise performance. Years of professional tuning high-powered race vehicles and intimate knowledge of the VW & Audi engines results in a wicked fast car on the street or the track. Your new software tune is easily uploaded to your factory installed ECU (engine control module) without touching a wrench in your own driveway. Multiple tunes are available to match your stock or installed aftermarket hardware.
You will also need the Integrated Engineering IE POWERLink Cable to flash your car.
Stage 1- Gain 73hp on stock hardware
The Stage 1 is engineered to release hidden horsepower and torque on completely stock hardware. Obsessive development delivers power gains smoothly across the entire powerband without adding a single aftermarket part. For those wanting more out Stage 1, the choice between 91 & 93 fuel octanes is included and the ability to adapt to minor bolt-on modifications, such as an intercooler, intake, and turbo inlet pipe. Low torque (manual trans w/ stock clutch) and high torque (DSG trans or upgraded clutch) files are both available.
Stage 2 - Up to 327hp with a matching hardware upgrades
Stage 2 is calibrated to take your performance to the next level. By upgrading the restrictive factory downpipe you unlock the full power potential from your stock turbo engine. Required bolt-ons (downpipe, intake, and intercooler) can be installed over a single weekend to match the tune -instantly transforming your MK7 GTI/GLI, or 8V A3 from a peppy street car into a true motorsport monster with 327HP and 399TQ!
Required Bolt-On Parts to achieve Stage 2 tune are:
IS38 Turbo - Go all out with a turbo upgrade for 415HP
Stage 2 completely taps out all the available power from the factory IHI IS20 Turbo. Upgrading to an IHI IS38 Turbo boosts your car to the next level, delivering up to 415HP & 457TQ! IE's IS38 Turbocharger Tune has been obsessively perfected to unleash the full potential from your turbo upgrade while remaining factory-like comfort and reliability. With your choice of 91, 93, or 104 octane, get ready to spin those tires with an addictive power and torque gain!
2019+ GTI is not currently supported for IS38 Tunes. -Coming Soon.
Requires the additional Integrated Engineering Audi Volkswagen 2.0T/1.8T MK7 8V Gen 3 Engine Turbo Inlet Pipe (A3, S3, TT, TTS, Alltrack, Golf, GTI, GLI, Passat & Tiguan) on top of the Stage 2 Bolt-on parts.
How to install the tune
IE's own in-house developed POWERlink cable and software gives you the freedom to quickly flash your car’s engine control unit (ECU) or transmission control unit (TCU) with your new IE performance tune. The cable simply plugs into your vehicle’s OBD-2 port, from there simply follow the on-screen directions to quickly upload the tune. Adding horsepower is as easy as clicking FLASH NOW!
The flash tool also grants instant access to upgrade tune stages, switch fuel octanes, flash back to stock, perform engine diagnostics, read/clear codes and gather high-quality operating data via logging.

Rest of World (ROW) Support
IE tunes are designed and written on North American (NA) vehicles. Although IE does offer ROW purchases of software files, some ECUs available only in certain countries or markets may not be supported in our current file library.

Increased RPM
IE MK7 GTI/GLI & 8V A3 performance calibrations continue to make power and torque above the factory rev limiter. To take advantage of the larger power band, factory rev limits have been raised to 7000RPM. On automatic equipped cars, our DSG Tune is required to unlock these higher RPM ranges. DSG Calibration will shift slightly before (6900RPM).
