  • How do I install Integrated Engineering ECU / TCU tunes on my VW / Audi?

    In order to install the tunes, you will need to also purchase the Integrated Engineering POWERlink Flash Cable, which you can find HERE.  You will be able to flash your engine and/or transmission with the software that is included with your POWERlink Flash Cable.


IE ECU Stages for your VW 2.5Lengine are available as Stage 1 stock engines or with an IE intake manifold upgrade for Stage 2.  Read below to determine the best stage for your build!

The IE Stage 1 VW 2.5L tune delivers an aggressive power upgrade without having to install any hardware modifications.  Perfect for customers looking for a jump in power without adding any additional hardware.  In a matter of minutes, the vehicle will be much more enjoyable to drive with a boost in performance.  This tune also deals with many factory tune annoyances on the 2.5L engine such as throttle hesitation, rev hang, and response that greatly adds to drivability feel.  Designed for use with regular pump 91/93 octane.

The IE Stage 2 VW 2.5L performance flash is designed for customers looking to maximize the performance of the factory engine with an IE Performance Intake Manifold (Sold Separately).  IE Stage 2 software fine-tunes the ECU calibration to match the manifold flow characteristics.  Stage 2 results deliver massive power gains across the powerband, fully realizing the 2.5L engine's potential without adding boost or high compression pistons.  *IE Stage 2 Manifold Tune is only for vehicles with electric power steering.
