  • 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 the tuning form below and mail it in with your ECU. If you're doing a remote flash you can email it.
