Returns & Replacements Policy

Here's exactly how returns and replacements work at SleepyTuned — what's covered, what isn't, and what to do if something you bought from us arrives broken or wrong. Short version: digital products are final once delivered, and defective hardware gets replaced fast because we ship your replacement as soon as your return is on its way back to us.

Digital Products & Services

Tunes, tune revisions, tune files, and Map6 services are custom digital work — once your file is delivered, it can't be "returned," so all digital sales are final.

That doesn't mean you're on your own:

  • Something wrong with how the car runs on your tune? Open a revision request and we'll work through it with you.
  • Any other issue — delivery problems, questions, something not adding up — contact support and we'll get you sorted.

Physical Hardware

This covers EK1 devices, plug-and-play TCUs, and any other hardware we ship to you.

We don't accept change-of-mind returns — please double-check compatibility and fitment before ordering (and ask us if you're not sure — we're happy to help before you buy).

If your item arrives defective or we sent you the wrong thing, we'll make it right with a replacement. Here's how that works:

The Replacement Process

  1. Contact support and tell us what's wrong.
  2. We confirm the fault with you — usually just a quick back-and-forth.
  3. We authorize the return and give you the address to ship it to.
  4. Ship it back via standard ground (UPS Ground or USPS Ground Advantage) and keep your receipt.
  5. Send us the receipt and tracking number — your replacement ships as soon as we have them. We keep stock on hand, so you're not waiting for your old unit to arrive before the new one goes out.

Return Shipping Is On Us

We reimburse your return shipping to your original payment method — just include the receipt when you send us your tracking info.

One thing to know: we reimburse standard ground rates only. If you'd rather ship it back expedited or overnight, that's totally fine, but the difference is your cost — we'll refund what standard ground would have run.

30-Day Claims Window

Defect claims need to be opened within 30 days of delivery. If something seems off with your hardware, don't sit on it — reach out and we'll take a look.

Mail-In Units (Your Own ECU or TCU)

If you're sending us your own ECU or TCU for service, shipping works like this:

  • Getting it to us: you cover the inbound shipping.
  • Getting it back to you: that's on us — return shipping to you is included.

Questions?

If you're not sure whether your situation is covered, just ask — reach out to support and a real person will walk you through it.
