iE's B9 2.9T ECU Tunes are fully realized performance calibrations that deliver incredible power figures and endless smiles. However, the engine is only part of the fun as your transmission is also in charge of delivering the power to the road. Upgrading your transmission computer (TCU) tune increases shift speed, torque limit maps, line pressure, and launch control functions, to further deliver increased performance. As a result, the iE TCU Stage 2 Tune will significantly transform every aspect of your RS5, or RS4, delivering faster launches, higher Gs, and further improved acceleration.
