IE VW & Audi 2.0T TSI / TFSI EA888 Gen 1/2 Performance ECU Tune | Fits VW MK6 GTI, Jetta, GLI, B6 Passat, 3C CC, 5N Tiguan, Audi 8P A3 & 8U Q3

Unlock the performance potential of your Volkswagen or Audi with the Integrated Engineering (IE) 2.0T TSI / TFSI EA888 Gen 1/2 Performance ECU Tune. Developed for compatible turbocharged VW and Audi applications, this ECU software upgrade optimizes engine calibration to deliver increased horsepower, improved throttle response, stronger acceleration, and enhanced driving performance.

Designed for enthusiasts seeking a flexible performance upgrade, IE offers multiple tuning stages to accommodate different hardware configurations and performance goals. Whether you're starting with a completely stock engine, upgrading your intake and exhaust system, or installing a larger BorgWarner K04 turbocharger, the IE tuning platform provides dedicated calibrations to support your build.

The Stage 1 ECU Tune delivers up to 257 HP without requiring additional performance hardware. Stage 2 increases advertised output to 281 HP with the appropriate supporting modifications, while the K04 Turbo calibration offers up to 391 HP when paired with the required turbocharger and performance components.

Integrated Engineering's POWERlink flashing system allows compatible ECU and TCU calibrations to be installed through the vehicle's OBD-II port. Drivers can also switch between supported octane files, upgrade tuning stages, return to the factory calibration, access diagnostic functions, and collect engine operating data.

Unlike newer IE mobile-flashing applications, this EA888 Gen 1/2 tuning platform requires a compatible Windows 10 or newer laptop or tablet. Mobile phone app flashing is not supported for these engine ECUs.

Manufactured by Integrated Engineering, this performance ECU tune provides a comprehensive upgrade path for compatible Volkswagen and Audi 2.0T owners seeking increased power while retaining the appropriate factory engine-management safeguards.
