Tuning Solution for DQ381 with factory 401 bootloader

After extensive testing TuneZilla is proud to release our solution for DSG equipped MK8 R and GTI models with the “locked” 401 Bootloader. This is a physical hardware change. By removing the mechatronic unit and swapping to our pre-flashed bootloader, users can enjoy more features not available from the factory.

Please Note: The TCU tune comes pre-loaded on the unit and was designed to work with our ECU tune. If you have another company’s ECU tune, please ask them for a high TQ file as low TQ options can limit the performance of both ECU and TCU tune.

Running another company’s TCU tune will void the warranty offered on our 301 Bootloader units.

Warranty Coverage:
The TZ Bootloader is covered for 1 year, or 10,000 miles (whichever occurs first) and is limited to the bootloader only. TuneZilla does not cover any hardware failure beyond the bootloader. Installing the TZ Bootloader may void your factory warranty on transmission components. In the event of a failure, TuneZilla may replace or repair the bootloader unit at their discretion. Warranty coverage will be void if a third party software has been flashed to the bootloader. TuneZilla is not responsible for labour costs associated with install or removal.
