  • We do not offer tuning for emission delete, we do not disable catalytic converter or secondary air pump systems. 
  • We do not offer tuning services to the state of California.

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.

Please print out this form and mail it in with your DME. DME will not be flashed until the form is filled out and sent to us. Thank you.
