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.
(NOTE) 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.
