Performance Stage 1 ECU Software Precisely Engineered for your MK8 GTI.  This vehicle has added support through UniCONNECT+ which allows you to program your own vehicle right in your own garage.

Unitronic software is flashed directly through the (OBDII) diagnostic port of your vehicle (10-15 minutes).

Unitronic Stage 1 Performance Software is precisely calibrated for use with 91 oct/95 ron fuel and provides huge power gains over stock while maintaining an OEM-like driving experience with exceptional reliability.

Unitronic® Stage 3 ECU/TCU Software is available for the MK8 GTI® equipped with the 2.0TSI® EVO4 engine and Garrett PowerMax Turbocharger upgrade. With testing and validations completed, power outputs on the MK8 GTI are now increased by up to +204HP / +141LB-FT with Unitronic Stage 3 93 octane Performance Software for a total of 470HP / 425LB-FT. Stage 3 E85 support for the Garrett PowerMax Turbocharger is currently in development and coming soon. These new calibrations also include a new Start/Stop feature, which enables the vehicle to now remember the last set position and high-speed data logging via UniCONNECT+ for customers looking to gain greater insights about their vehicle's true performance as well.*
