There are several ways to install software
1) Purchase a Flashzilla Pro from our website: https://tunezilla.com/fzpro
2) Contact and book an appointment through a distributor: https://tunezilla.com/dealers
3) Bench flashing: The DDE (aka ECU or ECM) will need to be removed from your vehicle and either shipped to us in BC, Canada, or tuned through a distributor with the appropriate hardware.
If you are pulling the DDE (ECU) out of the vehicle for the tune, then please ensure that when you re-install it later, that the connector/latch is completely closed!
