Why We Offer Free Tuning?

How are we able to provide tuning for free? The tuning map is created once and then adjusted based on each customer’s needs. For example, if a customer has made modifications in the past or wants something unique, we customize the tune accordingly. This process is the same regardless of where you buy the tune. As a company, we thought, “Why should we charge for something that doesn’t cost us much to produce each time?” It’s 100% possible to offer it for free, so why not do something different? Isn’t that the whole purpose of a company?

If a company is created just to replicate what already exists in the market without making any meaningful changes that benefit customers, why should it even exist? We believe in change, and we believe in providing exceptional value to our customers.

Important Information about the Tune

How does tuning work?

Tuning involves adjusting your vehicle's engine control unit (ECU) to enhance performance, fuel efficiency, or other preferences. It can modify the way your engine performs by changing settings like fuel/air ratios, ignition timing, and turbo pressure.

How We Build the Advanced Custom Tune for You

When you get started with us, we’ll ask for a few details about your truck—like the VIN, make, model, and any unique setups. With that info, our tuning pros get to work, building a custom tune specifically for your truck. We’re talking about maximizing horsepower and torque and ditching those emissions system limits entirely. So, once it’s installed, no more dealing with DEF, no more annoying emissions lights popping up on your dash, and you’ll be able to tow some serious loads with confidence.

And here’s the best part: this whole process is all part of our service. No extra fees and we are the only company doing that.

What does the tuning device do?

The tuning device connects to your vehicle's OBD-II port and communicates with the ECU. It allows you to upload custom settings (or “tunes”) to adjust your engine's performance. These devices also allow for data logging, diagnostics, and monitoring of engine performance.

I'm not a computer guy, and I don’t know how to install EFILive. What do I do?

Don’t worry—we’ve got you covered! If you’re unsure about installing EFILive, we’ll handle everything for you. Once you receive your device, just send us the device serial number (usually located on the back). After that, we’ll create your custom tune within 24 hours or less and notify you via email when it’s ready.

We’ll also send a link to book a meeting so we can access your computer through AnyDesk and flash your truck for you—quick, easy, and hassle-free!

And if you’d like to handle the installation yourself, no problem. We include a step-by-step installation guide with every purchase, so you can follow the instructions whenever you’re ready. Our goal is to make your experience as smooth and comfortable as possible, with flexible options to suit your needs.

I had an absolutely amazing experience with this company. Their customer service truly went above and beyond to make sure everything was perfect. I ordered an EFILIVE from them. Once I received it I booked a meeting so they can flash my truck, they used my Anydesk to remotely flash my truck it only took 25 minutes, and the whole process was seamless.
The only small hiccup was that they sent me the wrong switch, but honestly, their support team handled it like pros. They immediately jumped on it, shipped out the correct one, and I had it in my hands within three days. Mistakes happen, but the way they resolved it was impressive and shows they genuinely care about their customers.
Their support is unmatched, and I’m recommending this company to everybody I know. These guys are the real deal!

These guys are legit amazing. I needed help with my 2015 Duramax, and they made the whole process ridiculously easy. Their support team walked me through the first steps over the phone, then hopped on anydesk to remotely help me program EFILive. It was smooth, quick, and completely stress-free. The tune? Absolute perfection. I had a specific request I needed, and they didn’t just listen they nailed it. It’s rare to find a company that’s this dialed into what their customers need. I can’t say enough good things about these guys. If you need expert help, look no further. Highly recommend.

I just wanted to share my experience and thank you for your outstanding service. I run a shop, and before working with you, I was dealing with The Diesel Dudes. Let me tell you, their support was a nightmare. I was trying to install efilive for a customer, but I kept getting an error. When I called them for help, all they said was, "Open a support ticket." I did, and they responded 24 hours later—by then, the customer was already frustrated and rushing me to get the job done. It was horrible.
What made it worse was that I paid a premium price expecting premium service, but all they cared about was sales. When it came to placing an order, they answered the phone immediately, but when I had a problem? Nothing. It was such a disappointing experience.
That’s when I decided to give Diesel Patriots a try. Honestly, I was hesitant at first because your prices seemed too good to be true, but eventually, I said, "Screw it," and placed an order. I’m so glad I did! The shipping was average—it took five days for my EZ Lynk to arrive—but that was fine by me.
Installing it was pretty straightforward, but I wanted to be absolutely sure I was doing everything right. So, I gave you guys a call. To my surprise, someone answered right away, and the guy I spoke to was incredibly nice and helpful. He walked me through the setup step by step over the phone. Once my truck started flashing, he told me, "When it’s done flashing and you’ve installed the DPF & CAT delete, call me back so we can test it together."
But life got busy, and I completely forgot to call back (haha). To my surprise, you guys actually called me the next day to follow up! I was blown away by that level of service. It was late by the time I finished, but the fact that you reached out just shows how much you care about your customers.
I can’t thank you enough for making this such a smooth and pleasant experience. You guys are amazing, and I’ll definitely keep buying from Diesel Patriots. Your support and service are miles ahead of the competition.
Thank you so much for everything!

I spent over a month searching for the best company to buy from, and I decided to go with these guys because they had the best price and seemed to provide full support. I’m not a computer guy, so having someone guide me step by step was exactly what I needed.
I purchased Efilive from them, and it arrived just six days after placing my order. I booked a meeting with their team, and they remotely helped me through Anydesk, flashing my truck for me and making sure everything was done right. The process was smooth and ea
