ECU Tune Stage 2

The Integrated Engineering Stage 2 ECU tune is designed to significantly enhance the performance of your Audi 3.0T engine, providing a broader powerband, a higher rev limit, and increased power and torque. This tune also features more aggressive exhaust overrun and crackles in Dynamic mode, and enables crackles for free revving in park or neutral, contributing to a more aggressive sound profile. This tune requires specific hardware upgrades, including downpipes, an intake, and intercooler upgrades, to achieve its full potential. The Stage 2 tune includes the Stage 1 TCU tune, which is required to manage the increased torque output of the engine. The POWERlink Flash Tool is also required for flashing the ECU and TCU, and older V3 POWERlinks are not compatible; a V4 model is necessary. The tune is permanently registered to the vehicle's ECU upon purchase and is non-transferable, except in the event of a vehicle transfer of ownership. Free updates for tune revisions, new octanes, standard features, and software updates are included. The POWERlink Flash Tool can be used on up to 5 different vehicle VINs, with tunes sold separately for each VIN. Some transmissions on 2021-2024 B9.5 models may have advanced security locks that prevent tuning, requiring a specific unlock procedure.
