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.

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.

Does the EZ Lynk have its own screen?
No, it doesn’t. You can control it using any Apple or Android device through the Auto Agent 3 app.

How do I get my tune file?
The EZ Lynk operates via cloud software. Once it's connected to your OBD-II port, it recognizes your VIN and displays your available tunes.

Does the tuner need to stay connected?
Once the delete tune is applied, the EZ Lynk can be unplugged. However, it needs to stay plugged in for other features. If you're using the Shift on the Fly feature, only the switch and correct tune file need to be installed.

Can I revert to OEM/Factory settings?
Absolutely! You can revert back to factory settings directly through the tuner whenever needed.

Is it necessary to delete all emissions parts?
The DPF must be deleted, but the tune shuts off all emissions systems. You can unplug sensors and wiring where applicable. While EGR deletes are optional, they're highly recommended for maximum reliability. At least , unplug the EGR sensors.

The EZ Lynk comes with custom delete tunes.

After your purchase, you will receive a form that you have to fill out with the necessary info of your truck, like VIN, make, and year. This way, we can preload your custom tune on the device so you receive it already preloaded. You just have to plug it in, and you’re all set.
