Sales Policy

By placing an order with Fummins Tuning, you acknowledge and agree to the policies below. These policies are intended to keep ordering, shipping, tuning, and technical support as straightforward as possible.

​

Orders, Changes & Discounts

Once an order has entered processing or shipped status, it is no longer eligible for retroactive discounts, coupon adjustments, or refunds due to a missed coupon or promotional code.

If an order change requires a partial refund, any non-refundable payment-processing fees charged by our payment provider may be deducted from the refunded amount.

​

Refunds & Store Credit

All sales are final and non-refundable.

Hard parts, electronic devices, and other physical products are covered under the applicable manufacturer’s warranty where provided.

If an order is no longer needed, the value of the order may be issued as store credit for up to one year from the original order date.

Orders that remain unused, unclaimed, or unresolved for more than one year may be considered forfeited and closed.

​

Shipping

Items shipped directly from Fummins Tuning are insured.

Items drop-shipped from a supplier are subject to that supplier’s shipping and claims policies. If a drop-shipped item is lost or damaged in transit, a claim may need to be submitted with the shipping carrier or supplier.

A different shipping carrier may occasionally be used when an item is drop-shipped or when circumstances require an alternate shipping method.

Please inspect your order when it arrives. If an item is damaged, defective, or incorrect, contact us as soon as possible so we can evaluate the issue and help get it resolved.

​

Tuning Order Fulfillment

Tuning orders are typically fulfilled within 24 hours Monday through Friday.

Orders placed outside normal business hours, late in the day, or on weekends may be completed on the following business day.

​

ECMs Locked by Previous Tuning

If your ECM is locked by another tuner, device, or previous software and cannot be flashed normally, we will help where possible with the unlocking process.

Additional programming, shipping, unlocking, or service fees may apply depending on the situation.

​

Cummins Swap & Transmission Tuning Revisions

Every Cummins swap is a little different. Vehicle configuration, engine setup, power level, gearing, tire size, and other changes can all affect how the vehicle behaves.

Because of this, revisions are common and are considered a normal part of the tuning process. We are happy to work with you to get the vehicle operating properly.

When requesting revisions, please follow the data-logging instructions in the user guide and provide as much information as possible. Good information and accurate logs allow us to make revisions much faster.

Swap transmission tuning support is valid for 90 days from the original order/base-tune date. After this period, additional tuning may require a retune fee. Retune services are available through the Fummins category of the store.

Minor changes, such as tire-height adjustments, may still be handled at no charge when reasonable.

​

Tuning File Modification

Tuning files supplied by Fummins Tuning may not be edited, altered, unlocked, redistributed, or modified without authorization.

Unauthorized modification of supplied tuning files will result in loss of technical support and refusal of future tuning services.

​

Communication & Technical Support

We offer several ways to contact us:

For tuning revisions, data logs, file-related issues, and problems that may require multiple troubleshooting steps, the Tech Support Portal is often the easiest way to keep all information together.

Please include your order and vehicle information whenever possible so we can assist you efficiently.

We ask that communication remain professional and respectful. We will work with you to resolve problems and provide the steps needed to move things forward. Abusive, threatening, or excessively vulgar communication may result in support or services being discontinued.

​

After-Hours & Weekend Flashing

Support availability is more limited outside normal business hours, particularly on weekends.

If you choose to flash or program a vehicle during these times, please keep in mind that assistance may not be immediately available if something does not go as planned.

Most flashing issues are resolved quickly with a corrected file, reflash, or some basic troubleshooting. However, there is always a possibility that a vehicle may remain unavailable until we are able to assist during normal business hours.

We do not typically fulfill tuning orders or provide regular tuning support on weekends, so please plan vehicle programming accordingly.

​

Policy Updates

Fummins Tuning may update or revise these policies as needed.

If you have questions regarding an order, shipping, tuning, or technical support, please contact us before placing your order.
