$100 Diagnostic Fee is due once your appointment is confirmed (not collected on this page). Diagnosis may include a vehicle road test. If the vehicle cannot be driven, the fee includes up to 25 miles of travel.

$500 Calibration Fee is only charged if calibration/tuning is required and approved, and is in addition to any cost associated with purchased TCM calibration rights (cost varies by platform). We confirm after review.

Proof of insurance is required prior to any road testing.

Next Step Acknowledgment

After review, we’ll contact you with next steps and (if needed) a link to pay the diagnostic fee to secure the appointment.
