Stage 3 ECU Big Turbo Performance Engine Tune

The Unitronic Stage 3 ECU Big Turbo Performance Engine Tune is a sophisticated software upgrade precisely engineered for VW/Audi 2.0L TSI engines. This tune is designed to reliably manage 20psi of boost on a stock engine, with the capability to achieve up to 600 HP. When using 93 octane fuel, expect up to 400 HP, significantly enhancing your vehicle's performance. This tune supports GT30-GT35 series turbos or similar sizes, and is compatible with the stock throttle body and stock cams. It does not require emissions deletes or a mafless setup, and it removes the speed governor. The RPM limiter is increased to 7100 with the stock head. For 6-speed manual transmission equipped GTI®, Jetta®/GLI® models in North America (CCTA/CBFA), spark-based launch control is available with user-selectable setpoints and 5PSI of boost off launch. Installation is made simple through Unitronic's UniCONNECT+ system, allowing users to flash their ECU from their home or garage. This system also provides diagnostic capabilities and the ability to flash back to stock. To ensure a smooth flashing process, Unitronic recommends using specific battery chargers. Significant hardware is required for this tune, including a Unitronic 2.0 TSI Gen1 (FWD) 3" Downpipe, a Unitronic 2.0 TSI Gen1 Intercooler Kit (MK5/MK6), a Unitronic 2.0L TSI High Output Fuel System, an upgraded exhaust system, and an internal wastegate on the turbocharger calibrated to 12PSI. The OEM MAF housing must be utilized in its original location and orientation, and an upgraded intake with OEM MAF size is required. For builds exceeding 400HP, upgraded rods are recommended, and a water/meth kit is advised to reach over 500HP. This tune fits various VW and Audi models from 2009-2017, including the CC, EOS, GTI, Jetta, Jetta GLI, Beetle, Passat, A3, and TT, all equipped with the 2.0L TSI engine.
