📦 Step-by-Step Mail-In Process

1. Download and complete the ECU/TCU Tuning Information Form
   Download the PDF Form
   Be thorough when listing your vehicle modifications, fuel type, and tuning preferences so we can calibrate your software accordingly.
2. Remove your ECU (and TCU if applicable)
   If your tuning package includes transmission calibration (PDK/TCU), the TCU must be removed and shipped along with the ECU. Contact us if you’re unsure how to remove it.
3. Include the completed form with your shipment
   Add your printed form and Shopify order confirmation to the box. Make sure your components are packaged securely.
4. Ship your ECU and/or TCU to:

5. Same-Day Turnaround
   We tune and return ship the same day your ECU/TCU arrives (if delivered by 10:30 AM EST). Return shipping method will match your inbound method (Ground, Overnight, etc.).
