Orders & Shipping

Demand is exceptionally high when ordering opens. We have seen approximately 300–500 people attempting checkout at the same time, while each week's inventory is limited by the number of units we can build and finish.

We cannot oversell units we cannot reasonably fulfill. We understand that missing a release is frustrating, and we appreciate your patience.

Shopify checks remaining inventory during checkout. If another shopper completes payment first and inventory reaches zero, Shopify may remove the item from your cart. Adding to cart is not a reservation. A successful checkout and order confirmation mean your order was accepted.

Use our Supported Vehicles & Product Finder to select your make, model and year. Check the connector-compatibility notes on the actual product listing before ordering.

Some older models have different connectors or drivetrain requirements, so year alone may not be sufficient.

Please contact Sales Support as soon as possible with your name, email address and order number. Changes and cancellations may not be possible after an order has entered processing or shipping.

Use our Support form and select Sales Support, or email office@eastmanresearch.com.

Select View My Orders to sign in securely through Shopify and see your order's status and any tracking information that's been provided.

If you checked out as a guest, use the “View your order” link in your confirmation email. If you can't find it, check your spam or promotions folder. Tracking may not show movement until USPS receives and scans the package.

Most often the shipping label has been created, but USPS hasn't scanned the parcel yet. Allow at least 24 hours for a new tracking number to begin showing activity.

We try to ship original VCMTUNER orders the same business day when possible. VCMTUNER II orders ship according to the release's stated fulfillment window. Shipping times are estimates and may vary with production demand.

Shipping to Canada is available, but customs, duties, tariffs and carrier handling fees may apply. Those amounts depend on the destination and applicable regulations and are generally the customer's responsibility.

See the import and tariff information for additional guidance.

Follow the return procedure on our Return Policy page. That policy currently directs customers to email office@eastmanresearch.com with “Return for Order #” in the subject and a brief explanation.

Package your complete unit securely in a 6×9 or 6×10 padded bubble mailer when appropriate and include your name and physical return address. Contact us before shipping if you need clarification.

Per our current Return Policy, please allow up to five business days after we receive the return for refund processing. Carrier delivery and local post-office pickup times can affect the schedule.

Products sold since September 2025 include a two-year warranty from purchase, subject to the published conditions. Orders placed before September 2025 have a one-year warranty.  Please see the Return Policy and Warranty page for details about repairs and replacements.
