Ironline Diesel

We specialize in 2011–2026 Ford trucks equipped with the 6.7L Power Stroke. Exact fitment and available tuning options can vary by model year, calibration, current modifications, and intended use. Use our Setup Finder or send us your truck’s information, and we’ll help you select the correct setup.

It depends on the option you select. We offer Tune Only for customers who already have a compatible EZ Lynk, EZ Lynk + Tuning, and Full Setup Packages that include the selected hardware and tuning. Exact contents depend on your truck’s year and the options chosen on the product page.

Our tuning is developed in-house by Ironline Diesel’s calibrators. Your files are selected from our proven calibration library and matched to your truck’s year, calibration, modifications, and intended use. They are not individually written from scratch for every VIN.

EZ Lynk is the device and mobile platform used to connect your truck with our technician account and deliver tuning files remotely. The AutoAgent connects to your truck’s diagnostic port and communicates through the EZ Lynk app. If you already have a compatible EZ Lynk that can be linked to us, select Tune Only. Otherwise, choose an option that includes the EZ Lynk device.

After ordering, you’ll submit your truck information and receive instructions for the next steps. If your order includes parts or an EZ Lynk device, those items ship first. Once your truck is ready, you’ll connect the AutoAgent and add Ironline Diesel as your technician in the EZ Lynk app. After your truck is linked and we have the required information, your files are delivered through EZ Lynk during our posted Monday–Friday file-delivery hours.

Many customers load their tuning files themselves through the EZ Lynk app using our instructions. Physical hardware installation requires the proper tools and mechanical experience. Installation labor is not included, and professional installation is recommended if you are not comfortable completing the hardware work yourself.
