Tuning and Scanning Power Strokes with the EZ-LYNK Auto Agent 3

If you own a 2008-2019 Ford F-250 or F-350 with a 6.4L Power Stroke or 6.7L Power Stroke diesel engine, there’s one upgrade that should be at the top of your list—and it’s not a turbo, exhaust, or tuner.

It’s the EZ-LYNK Auto Agent 3.

This little plug-in tool gives you full access to your truck’s brain. Want to see what your engine is doing in real-time? Check. Need to clear a check engine light without a trip to the shop? Done. Want to send engine data straight to your mechanic from the road? You got it.

Let’s break it down so you can see why the EZ-LYNK Auto Agent 3 is one of the best tech upgrades you can make to your Power Stroke.

The EZ-LYNK Auto Agent 3 is a small device that plugs into your truck’s OBD-II port—just like the scanner in your toolbox. From there, though, it connects wirelessly to the free EZ-LYNK app on your phone or tablet.

When you plug it in, though, you’ve got both a regular scanner that reads live engine data, pulls trouble codes, clears check engine lights, and even sends information directly to a technician or tuning partner.

And here’s the best part: no wires, no complicated menus, and no expensive shop visits for simple fixes, and we haven’t even talked about the “tuning” side of the EZ-LYNK yet, so keep reading…

Whether you're driving a 6.4L Power Stroke in a 2008–2010 F-250 or a 6.7L Power Stroke in a 2011–2019 F-350, the Auto Agent 3 is built for your truck. It works with both generations of engines, giving you deep insight into everything under the hood.

You’ll get real-time readings for:

• Engine oil and coolant temperatures
• Turbo boost levels
• Fuel rail pressure
• Regeneration status
• Transmission temps
• And more

It’s like having a full dashboard of professional-grade gauges—right on your phone.

Sometimes those CEL codes are something small—like a loose fuel cap or a sensor hiccup. Clear the code yourself and get back on the road. If it’s more serious, you can send a log file to your mechanic remotely, straight from the app. They can review it and even send updates or instructions back to you without needing to touch the truck.

Even if you don’t plan to tune your truck right now, the Auto Agent 3 is still worth owning. It ships as a “blank” device, meaning there’s no tuning pre-installed. But you still get all the features: live data, DTC reading and clearing, and app control.

Down the road, if you decide to tune your 6.4L or 6.7L Power Stroke, all you need is a tune from a certified EZ-LYNK tuning partner. And with the optional Shift-On-The-Fly switch, you can change power levels without ever turning off your truck.

Why Power Stroke Owners Love It

Owners of Ford Super Duty trucks love the Auto Agent 3 because it puts them in control. Instead of guessing or waiting on a shop, you get answers now. Instead of running blind while towing, you can see temps and boost levels live. And instead of wondering when the next regen is happening, you can track it yourself.

For any 2008–2019 Ford F-250 or F-350 Super Duty with a 6.4L or 6.7L Power Stroke, the EZ-LYNK Auto Agent 3 is one of the smartest upgrades you can make. It saves time, gives peace of mind, and puts powerful data right at your fingertips.

Whether you're towing heavy, daily driving, or just want to stay ahead of maintenance, this tool has your back.
