The result is a noticeable improvement in acceleration, without any sacrifice in comfort or reliability.

In addition, End User Flashing allows Dynamic+ Performance Software customers to receive and install software updates and revisions, flash back to stock, or upgrade to the next stage of performance software for their vehicle.

TCU COMPATIBILITY

2022+ MK8 GTI model-year vehicles are equipped with TCU flashing protections that prevent OBD unlocking and tuning, known as the 401 bootloader. In order to unlock your TCU, select the Bootloader Unlock Harness (BLU) at checkout when also purchasing your TCU tune. This harness allows for a one-time unlock, enabling OBD flashing via 034SPI, allowing you to flash with your Dynamic+ TCU tune. Learn more about the Bootloader Unlock Harness (BLU) here.

BLU is only compatible with 034SPI and requires that you own a 034Motorsport TCU tune.
