Shipping & Dispatch

Tuner Depot dispatches in-stock physical orders within 2 business days from our British Columbia warehouse. Most North American orders arrive within 2 to 7 business days after dispatch via expedited ground. International orders take 5 to 14 business days depending on destination and customs clearance.

Tuner Depot ships globally from a single warehouse in the Pacific Northwest, British Columbia, Canada. The majority of our orders go to the United States and Canada, but we regularly ship to Australia, the UK, Mexico, and the EU. We do not operate US-side warehouses or third-party drop-ship locations.

Yes. Tuner Depot ships across the United States from our British Columbia warehouse, with most US orders arriving within 3 to 6 business days after dispatch. We also offer a Tariff Protection Plan that covers tariff and brokerage cost increases for US-bound shipments so your landed cost stays stable.

US-bound orders may incur duties or brokerage fees collected by the carrier on delivery. Tuner Depot's Tariff Protection Plan covers eligible tariff and brokerage cost increases at checkout, so the price you pay at order time is the landed cost. See /pages/tariff-protection-plan for the full coverage terms.

Custom tuning

After you order a custom tune, you submit your stock tune file along with your VIN, year/make/model, engine code, transmission, and modifications. Tuner Depot's in-house calibration team builds your custom tune and emails it back within 1 business day of receiving your stock file.

Tuner Depot aims to deliver your custom tune file within 1 business day after you submit your stock tune file. Submissions made on weekends or holidays are processed the next business day. You must include your order number, VIN, engine code, transmission, and modifications list to avoid delays.

You need to submit six items: order number, year/make/model, engine code (e.g., 6.7L Cummins), complete 17-character VIN, transmission type, and a full list of modifications including injectors, turbo, exhaust, and intake. Missing or incomplete information is the most common reason for tune-delivery delays beyond 1 business day.

No. All custom tune files, tune devices, and tune-related hardware sold by Tuner Depot are final sale. We do not accept returns, exchanges, or refunds on tuning products under any circumstance because each tune file is calibrated specifically to your VIN and modifications. Verify your vehicle compatibility before ordering.

Fitment & Compatibility

Every Tuner Depot product page lists year, make, model, engine code, and transmission compatibility under "Fitment." For all-in-one kits, every component must match your platform — not just the truck. If you're unsure, submit a tech ticket at /pages/contact-us with your VIN and we'll confirm fitment within one business day.

Tuner Depot supports Cummins 5.9L and 6.7L (1998.5–2024), Ford Powerstroke 6.0L, 6.4L, 6.7L, and 7.3L (1994–2024), GM Duramax LB7 through L5P (2001–2024), Jeep and Ram EcoDiesel 3.0L, and Mercedes Sprinter 2.7L and 3.0L OM642/OM651. Other platforms can be confirmed by tech ticket.

Pre-orders & Stock

When an item is out of stock but on order with the manufacturer, Tuner Depot offers it with a "Pre-Order" label. Pre-order purchases ship as soon as the item arrives at our warehouse, typically 2 to 8 weeks depending on the manufacturer's lead time. You're charged at the time of purchase.

Tuner Depot ships in-stock components of your all-in-one kit immediately and dispatches the back-ordered item separately when it arrives. For example, if your tuner and delete pipe are in stock but the EGR delete kit is on pre-order, you receive two shipments at no additional cost.

Returns & Warranty

Tuner Depot accepts returns only on items proven to be defective due to manufacturing fault, with an approved Return Merchandise Authorization (RMA) number issued in advance. We do not accept change-of-mind returns. Custom tuning, exhausts, race pipes, turbochargers, and EGR kits are final sale and non-returnable.

Email or call us at 866-401-6313 with your order number and proof of the manufacturing defect (photos, video, or diagnostic readout). Tuner Depot's support team reviews and issues an RMA number within 1–2 business days. Returns sent without a valid RMA number and our prepaid label cannot be processed or refunded.

All custom tuning (files and devices), exhaust systems, race pipes, turbochargers, and EGR delete kits are final sale at Tuner Depot. These five categories are non-returnable, non-refundable, and non-exchangeable. Verify fitment and vehicle compatibility before purchasing — submit a tech ticket if you're unsure.

No. Tuner Depot does not offer physical or hands-on technical support. If you are not fully confident installing and troubleshooting diesel performance parts yourself, you should have a trained diesel mechanic handle the installation. You're welcome to email hello@tunerdepot.com with questions, but on-call diagnostic support is not available.

Tracking & Shipping Issues

Your tracking number arrives in an emailed invoice as soon as Tuner Depot's fulfillment team processes your order and creates the shipping label. If it has been four business days since you placed the order and no email has arrived, contact hello@tunerdepot.com — there may be a shipping snag or an email address issue.

Tuner Depot creates and emails your tracking number as soon as the shipping label is generated, but the package isn't scanned until it reaches the carrier's warehouse. Until then, tracking will say "check back tomorrow." The package has been picked and is in transit — scans typically begin within 1–2 business days.

First, check with neighbors and household members, and look for safe-drop locations near your door. Then contact the carrier with your tracking number to open a delivery investigation. If unresolved within 48 hours, email hello@tunerdepot.com and we'll help file a claim. Carrier investigations typically take 5–10 business days.

Contact Tuner Depot immediately at hello@tunerdepot.com before installing or using the product. We'll ask for photos showing the damage and the original packaging, and we'll guide you through the carrier claim and replacement process. Reporting damage within 48 hours of delivery gives the strongest chance of full resolution.

Tuning Tech Knowledge

Yes. Any emissions-related warning messages currently displayed on your dash must be cleared before you flash a delete tune. No tuner will clear these codes during the flash, and once the tune is installed the message stays stuck on the dash permanently. Resolve dash messages first, then tune.

A complete delete needs three things: a delete-capable tuner to recalibrate the PCM, a DPF delete pipe or full delete exhaust to replace the factory filters, and ideally an EGR delete kit to prevent coolant leaks and intake soot buildup. Install the emissions-off tune before physically removing any emissions hardware.

EGR systems route hot exhaust back through a coolant-cooled heat exchanger that wears, cracks, and leaks coolant into the combustion chamber. On direct-injection diesels like Cummins, Powerstroke, and Duramax, EGR also builds soot on the intake valves, causing power loss and poor fuel economy. Deleting eliminates both failure modes.
