APR DQ381 7-Speed DSG and S Tronic TCU Upgrade
APR is pleased to present the ultimate Transmission Control Unit (TCU) Upgrade for the DQ381 7-Speed DSG / S-Tronic Transmission!
APR’s TCU Upgrade dramatically improves upon the DQ381 transmission’s function, drivability, and performance through a myriad of enhancement and custom features. Normal daily driving is smoother as we’ve improved upon the normal quirks and complaints associated with the driving experience. Sporty driving is far more capable with increased torque capacity, clamping pressure, faster shifting times, more capable launch control, and more, handily shaving .2 seconds off our Stage 2 S3’s quarter mile time! Both are optimized to deliver faster acceleration by matching the power output delivered by our ECU Upgrade. This all comes with customizable features you can choose while flashing the TCU to personalize the transmission to your desire! Lastly the software loads to the factory TCU through the OBD-II port, resulting in a clean and headache-free install.
