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) with IE's Stage 2 TCU tune increases shift speed, torque limit maps, line pressure, and launch control functions, to further deliver increased performance. As a result, horsepower and torque levels are raised and acceleration is greatly improved to create complete and well-rounded drivetrain performance from your Audi RS5 or RS4.
