Frequently Asked Questions

Q: How long will it take to get the part I ordered?
A: Shipping speed depends on your chosen shipping method. We have several shipping options ranging from Free Economy Shipping to Next Day Air. Keep in mind ALL orders have a processing time. You are paying for the shipping service from when the order ships, not from the order date. We do our best to get all orders out the same or the next business day.
Q: What are some upgrades or maintenance items you recommend for my truck?
A: There are tons of upgrades for every truck. We suggest exploring our blog, it's loaded with information. You can also give us a call at 888.99.DIESEL, email us at sales@dieselpowerproducts.com, or use the livechat feature on our website.
Q: Should I spend money on my current truck or just buy a new one?
A: While it can be tempting to think of getting a brand-new truck, it's important to weigh the costs. At the moment, new trucks are incredibly expensive due to various market factors. Often, investing in maintenance or upgrades for your current truck can be far more cost-effective than purchasing a new one. Not only can you potentially extend the lifespan of your truck, but you'll also avoid the significant depreciation hit that comes shortly after buying a new vehicle. Before you make a decision, consider the overall health of your current truck, the cost of the necessary repairs, and the potential long-term savings.
Q: How do I make sure a part will fit?
A: The best way to know if a part will fit your application is by verifying the application and the part fitment on our website. Still, have questions? Talk to one of our experts.
Q: Do you have any performance upgrades that won't void my warranty?
A: Absolutely, there are some areas you can upgrade right away to customize your truck to your liking without setting off alarm bells at the dealer, and luckily, that can involve adding horsepower as well.

If you place your order late in the day (after 3pm PST) or the product has to be drop shipped from the manufacturer, you may receive your tracking number the next day. If you haven't received it by the end of the next business day, give us a call and we will get it for you.

A: Yes! Through our Deferred Core Program, you can defer the typical core charge you'd normally have to pay upfront and be refunded upon returning your core part.

Q: How can I identify if a product on your website is CARB Compliant?
A: Every product on our website that is CARB Compliant will have a distinct "CARB Compliant" logo displayed. Additionally, an associated number that certifies its compliance will be found at the bottom of the product description.
Q: There's no "CARB Compliant" logo visible on the product's page. Is the product non-compliant?
A: Typically, products that adhere to CARB standards will show the "CARB Compliant" logo and its related number. If these aren't visible, it's probable that the product isn't CARB compliant. However, remember that CARB compliancy is relevant mainly for engine replacements or upgrades. Items like suspension or lighting are not subject to CARB approval. Still have questions?

Q: What is the difference between custom tuning and box tuners like the Edge Evolution?
A: Custom tuning and box tuners are both methods to adjust the performance characteristics of your diesel truck, but they differ significantly in their approach and level of customization. Custom tuning involves a specialist tailoring your vehicle's electronic control unit (ECU) settings to match your specific hardware upgrades, driving style, and performance goals. This process accounts for every detail of your vehicle's setup, resulting in optimal power, torque, and efficiency. However, this service requires specialized knowledge and can be more costly. Box tuners, like the Edge Evolution, are off-the-shelf products that offer pre-set tunes. These devices are user-friendly and usually come with several settings to choose from, such as economy, towing, or performance modes. While they can't provide the same level of customization as a custom tune, they're often sufficient for minor to moderate upgrades and tend to be more budget-friendly.
Q: I have a bad injector in my diesel truck, can I just replace one?
A: Yes, it's possible to replace only the faulty injector if you're in a pinch. However, it's generally recommended to replace the entire set of injectors at once as the other injectors are likely to have similar wear levels, and a single new injector among older ones could result in uneven performance. Replacing all injectors at the same time can also prevent you from having to repeat the labor-intensive process multiple times as other injectors may fail in the near future.
