We only offer one flashing type for this car (Bench Flash).

BENCH FLASH: Remove the ECU/DME and mail it in. We will create a full backup image of your ECU/DME without opening the lid or any physical damage to it. We then upload the tune. This is the safest way, as we can have a full backup of the entire ECU/DME content.
