Your vehicle information

The tunes we create for Ez Lynk are 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.

Shipping time

We process and ship all orders within 1-2 business days to all U.S. states. Once shipped, delivery typically takes 5-8 business days, depending on your location.

You will receive a confirmation email with a tracking number once your order has been dispatched. Please note that delivery times may vary slightly due to carrier schedules or external factors beyond our control.

Tuning & installation

Who makes your tunes?

Our tunes are made in-house by people who have worked with Duramax. We build and support the tuning for your truck ourselves.

Why we offer free tuning?

We build our tunes in-house, so we control the tuning costs. Different tunes and tuning adjustments are free with your tuning purchase.

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.

Transmission Tuning

Transmission tuning is included.

This tune will optimize shift points and line pressure for long term reliability of your transmission. It will also result in better fuel economy.

The most common questions about the EZ lynk

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.
