Terms of Sale

Last updated: October 2026

These terms apply to purchases on montetuning.com (the “Site”), operated by Summit Motion LLC (“Monte Tuning”, “we”, “us”). By placing an order you agree to them, together with our Privacy Policy and Product Notice.

  1. Products and fitment

    Monte GT and Monte GTR are aftermarket plug-in performance devices for vehicles with an OBD-II port (US 1996 and newer, EU 2001 and newer). Before you buy, check your vehicle in the fitment check on the Site or ask us — you are responsible for choosing the right product for your vehicle. Gains shown on the Site are “up to” figures that depend on the engine, its condition, fuel and driving; they are not a promise of a specific result for your car.

  2. Where we sell

    We do not ship to California. Monte products are not CARB-certified and are not legal for use on public roads on pollution-controlled vehicles in California or in states that have adopted California emissions standards. You are responsible for following the laws where you use the product (see the Product Notice).

  3. Orders and prices

    Prices are shown in the currency you select. Sales tax, where it applies, is calculated at checkout. We may cancel an order with a full refund if the product is unavailable, the price shown was clearly an error, or we suspect fraud. An order is accepted when we ship it.

  4. Payment

    Card and wallet payments are processed on our payment processor’s secure checkout; we never see your full card number. Pay-later options (such as Affirm or Klarna) are offered by independent financing companies — approval, terms and payments are between you and that company.

  5. Shipping

    Shipping is free. US orders ship with UPS and usually arrive in 2–4 business days; international orders ship with UPS Express or DHL and usually arrive in 5–10 business days. You receive a tracking number by email. Prices do not include import duties, taxes or customs fees for deliveries outside the United States: these are charged by the destination country and paid by the buyer on delivery. Risk of loss passes to you when the carrier delivers the package.

  6. Returns (30 days)

    You may return a product bought on montetuning.com within 30 days of delivery:

    1. Request the return from your Monte account (“Ask us”, topic Return) or email [email protected] with your order number and the reason — see Returns.
    2. United States: we email you a prepaid return label. Other countries: you ship the product back at your own cost with a tracked service; we email you the return address.
    3. Pack the product with all its parts in its original packaging.
    4. Once it arrives undamaged and in its original condition, we refund your payment to the original payment method within 7 business days.

    Products bought from other sellers are returned under that seller’s policy.

  7. Lifetime warranty

    Monte devices have a lifetime warranty against manufacturing defects for the original buyer: if the device has a technical fault, we repair or replace it. To claim it, open a warranty claim in your account or contact us; you send the device to us. The warranty does not cover shipping costs, accessories (such as the mount or cables), or damage from improper installation, accidents, water exposure or unauthorized modifications, and it cannot be transferred to a new owner. This warranty does not affect rights you have under the law. Details: Warranty.

  8. Using the product

    Install and use the product as described in its manual. Unplugging the device returns the vehicle to its factory settings; we recommend unplugging it before dealer service or diagnostics. Diagnostic and data features are for information only and are not a substitute for a professional inspection.

  9. Limitation of liability

    To the fullest extent permitted by law, we are not liable for indirect, incidental or consequential damages arising from the purchase or use of our products, and our total liability for any claim is limited to the amount you paid for the product. Some jurisdictions do not allow these limitations, so they may not apply to you.

  10. Disputes

    If something goes wrong, contact us first — most issues are solved within a few emails.

  11. Changes

    We may update these terms; the version on the Site at the time of your order applies to that order.
