722.9 7 Speed TCU Tune

The Weistec 722.9 7 Speed TCU Tune is engineered to significantly enhance the performance of your vehicle's transmission. This tune is applied via the Cypher Flash Tool, which allows for at-home flashing through the vehicle's OBD2 port, offering convenience and control over your car's software. The primary benefits of this TCU tune include faster and firmer shifts, achieved through reduced target shift times and increased line pressure. This heightened line pressure not only ensures more decisive gear changes but also increases the transmission's torque capacity by clamping the clutches more tightly, thereby reducing slip. Consequently, the transmission is better equipped to handle increased torque loads, and its overall lifespan is typically improved due to reduced internal wear. This upgrade is recommended for any supported vehicle, whether it is in stock form or has been modified for higher performance. To ensure compatibility with your specific vehicle, Weistec requires you to email your VIN to tuning@weistec.com. The tune is compatible with various Mercedes-Benz models, including the 2011-2016 SLK350 BlueEfficiency Base (R172) with the 3.5L V6 (M276 DE35) engine, among others listed on their compatibility chart.
