Orders placed Monday through Friday are shipped within one business day unless otherwise stated on the product page or communicated via email. Extra time may be needed to secure a replacement ECU (if ordered) for customers who require a spare. Preorders are an exception as well. Orders placed on an observable holiday, or after 1pm CST on a day preceding a holiday will be delayed by one (1) business day. International shipping is not available. Please contact us regarding shipment to PO Boxes​ prior to placing an order.


Physical goods sold by ASMW are custom items. As such, returns are not accepted for reasons other than a manufacturing defect that deems the product unable to be used as ASMW intended. If a manufacturing defect is found prior to install and the damage is not due to improper or attempted install then the return/exchange process can be initiated. The item will need to be shipped back to ASMW for inspection as part of the process. In the event of a manufacturing defect, a replacement item will be provided. Replacement is limited to fuel line kits and fuel injectors. ECUs and ECU modifications are not eligible for returns, refunds, or replacement.

Refunds are not made under any circumstances for custom items, ECUs that have shipped, deposits (unless deposit is for equipment rental), and/or other items that have been shipped. Refunds for cancelled tunes (scheduled, but not completed/shipped) and/or ECU modifications will be subject to a 15% cancellation fee taken from the full price of the tune and/or ECU modification not including the non-refundable deposit. If a tune and/or an ECU modification has already been performed and/or shipped, no refund will be given for any amount. It is understood by you that the work is unable to be undone and as such is a service rendered not eligible for refund or exchange. If you have placed an order for any tune and have not made prior arrangements for shipping, or are unable to physically travel to have the work performed (such as for a Custom tune), or if you have not verified you can be placed on the schedule to begin the process BEFORE placing your order, your payment will be refunded minus a $25 fee. Cancelled orders over $25 will be subject to a non-refundable $25 fee. Processing time for any applicable refunds may take up to 10 business days.

All sales are final for ECUs/stickers/vinyl/media.
