Thank you for filling out our calibration request form. Once your custom tunes have been created, you will be emailed a link to our Google Drive account where you will be able to download your custom tune files. By submitting this form I acknowledge the following: For gasoline applications, I acknowledge that check engine lights relating to emissions components (ie removing cats) will not be turned off via my custom tunes. For diesel applications, I attest my EGR/DPF systems will remain intact. Tunes will not be written if these systems are removed.
