EZ LYNK Auto Agent: What the Lifetime Support Pack Actually Buys You

If there is already an EZ LYNK Auto Agent sitting in your glovebox, the thing you are shopping for is the tune.

This is a tune pack for owners who already have an EZ-Lynk device.

That one sentence is the difference between what you are actually buying and what half the search results imply you are buying. A tune is the calibration your truck runs, and it gets cut for your truck instead of pulled off a shelf, which means the thing that decides whether this works out is not the hardware in your hand — it is whether the pack you order covers your platform.

Across the three packs in this guide, pricing starts at $899.00.

Three platforms, three packs, one decision to get right. We get it, the spelling is a mess out there — EZ Lynk, EZ Link, Ez-Lynk — and none of that matters once you know which truck you are ordering for.

What Happens After You Click Buy

An email lands, and it needs an answer. Your calibration gets built from information only you have: the serial number on your device, the VIN, and whatever is already bolted to the truck. Until that comes back, nothing is being built, because there is nothing yet to build it from.

Your Auto Agent Is Already the Hardware

Both generations of the Auto Agent are covered here, so the one you have been running is the one this loads onto.

It's a DSP5 tune for the EZ-Lynk Auto Agent 3.0 and is also compatible with the Auto Agent 2.0.

Same story on the Titan side of the catalogue, which is worth knowing if you bought your device years ago.

Fitment covers 2016, 2017, 2018, and 2019 Nissan Titan, and the tune is compatible with both the EZ-Lynk Auto Agent 3.0 and Auto Agent 2.0 hardware.

So an older device is not the problem people assume it is. The platform under the truck is the part that has to line up.

The Form Is the First Real Step

Clicking buy is not the moment the work starts. The moment the work starts is when you send the form back.

After you buy, we email a form to collect your tuner serial number, vehicle VIN, and any modification details, and we build your custom tune from that information.

Think of it as a build order rather than a receipt. A tune is cut to your truck the way a key is cut to a lock, and the blank is worthless until somebody has the shape.

What We Ask For, and Why

The serial number identifies your device. The VIN identifies the year, the engine and the emissions hardware the calibration has to work around. The modification list covers anything already on the truck that changes how it breathes — intake, exhaust, injectors, turbo work.

On a Chevrolet Silverado HD, the eighth character in the VIN is the engine code.^[1]

Two on that list are the ones people talk themselves out of mentioning.

In a common rail setup, diesel fuel is stored in a high-pressure rail that supplies fuel to each injector independently.^[2]

A variable geometry turbo optimises across engine speeds and loads, aiding engine braking, exhaust gas recirculation and thermal management.^[3]

Injectors and a turbo are not accessories. They are what the calibration talks to.

Leave something off that list and you have not saved yourself a step, you have ordered the wrong tune with your own hands.

The instinct to trim that list is understandable, and it is the wrong instinct. A modification you think is irrelevant is a modification somebody has to decide is irrelevant, and that somebody should be the person writing the calibration rather than the person filling in the form. If it changes airflow, fuelling or exhaust, it goes on the list. If you are not sure whether it counts, it goes on the list.

Not all trucks are made equal and may require additional adjustment to the custom calibration once received.^[4]

Specify your year and engine on the vehicle info form and we'll build the correct tune.

Do It the Same Day

Don't sit on the form, since your order doesn't ship until we have it.

Ten minutes at the kitchen table beats a week of refreshing your inbox. Pull the device out, write the serial down while you are looking straight at it, and send the thing back before you close the laptop.

What Is a DSP5 or CSP5 Tune?

Five power levels living on the device at the same time, with a rotary switch to move between them. DSP5 is the name on the Duramax and Powerstroke packs and CSP5 is the name on the Titan pack, and the difference that actually reaches you is which five levels you get. The switch itself is not included.

Five Levels, One Device

DSP5 means the tune carries five power levels on the device at once, and you shift between them on the fly using a rotary switch (a switch is required and not included), so no laptop is needed while you drive.

That is the whole appeal. One truck, five personalities, nothing to plug in between rounds.

The Switch Nobody Puts in the Cart

CSP5 means the tune carries five power levels on the device at once, and you shift between them on the fly with a rotary switch (the switch isn't included).

Read that last part twice, because it is the most common surprise on these orders. A five-level tune with no switch on the dash is a one-level tune until the switch turns up, so put it in the cart the day you order the pack and not the night before you want to use it.

Your Levels Depend on Your Platform

The ladder is not the same set of rungs on every truck, which matters the moment you start comparing two listings side by side.

The five levels run 20hp, 40hp, 60hp, 80hp, and 100hp, with GM trucks receiving the 150hp top-level tune.

On the Titan the ladder has the same shape without that extra step on top.

The five levels run 20hp, 40hp, 60hp, 80hp, and 100hp […].

The Powerstroke ladder starts somewhere else entirely, and this is the one that catches people out.

The five levels are 0HP with emissions deleted, +50HP, +100HP, +150HP, and +200HP.

Level one on a Powerstroke is factory power with the emissions hardware out of the picture. That is a real choice rather than a wasted slot, and plenty of builds never leave it.

Why Five Levels Instead of One

A single calibration has to be a compromise, because it is one answer to a question the truck asks differently depending on what you are doing with it that day. Five of them on the same device is the opposite arrangement: you pick the answer to suit the run.

So what is the calibration actually working with?

In diesel engines, internal combustion results in expansion of high-temperature, high-pressure gases, which in turn move pistons, transforming chemical energy into mechanical energy.^[5]

Most people settle into two of the five and treat the rest as headroom. A mild level for loading, unloading and moving around the pits, and one further up the ladder for when it is actually time to work.

The switch is what makes that practical. Turn it, and you are running a different calibration without opening anything or plugging anything in — which is exactly why the guys who skip the switch end up frustrated with a product that is doing nothing wrong.

The Three Packs, and What Each One Fits

Three listings, three platforms, and no overlap between them. Find your truck below, check the years against your title, and look at the price line — two of the three are spreads rather than single numbers, because what sits inside them is not identical from truck to truck.

EZ LYNK AUTO AGENT DPF Delete Tune | Lifetime Support Pack | GM/Chevy Duramax 2011-2016

Duramax owners get the version with the extra rung at the top of the ladder.

The EZ-Lynk DPF Delete Tune with Lifetime Support Pack lets you run your 2011–2016 GM 2500–5500 Duramax with deleted DPF (Diesel Particulate Filter) and EGR (Exhaust Gas Recirculation) components, so there are no codes, no regen, and no warning lights.

"No regen" is doing a lot of work in that sentence.

A Duramax comes with a Diesel Particulate Filter (DPF) that will filter or trap particulates.^[6]

On a Duramax, the DPF cleans itself as part of normal operation.^[7]

During self-cleaning there will be a change in the exhaust sound and engine idle speed.^[8]

Under certain conditions, such as idling or very short trips, the self-cleaning process has less efficiency and cannot be completed.^[9]

Manual regeneration can only be used when the DPF has become at least 90% full.^[7]

Sound like your day at the track?

Six model years, one listing, and the LML sits inside all of them.

The EZ LYNK AUTO AGENT DPF Delete Tune covers the 2011 through 2016 model years.

Where your truck lands inside that window is what moves the number.

Pricing on the Duramax pack runs $899.00 to $999.00.

EZ LYNK AUTO AGENT DPF Delete Tune | Lifetime Support Pack | Nissan Titan 2016-2019

The half-ton diesel nobody expected still has a following, and it has its own pack.

The EZ Lynk DPF Delete Tune for 2016–2019 Nissan Titan is a Lifetime Support Pack with a CSP5 tune that lets you run your Titan with deleted DPF (Diesel Particulate Filter) and EGR (Exhaust Gas Recirculation) components — no codes, no regen, no warning lights.

Four model years, and the window closes where the truck did.

The EZ LYNK AUTO AGENT DPF Delete Tune covers the 2016 through 2019 model years.

This is the straightforward one to order, because there is only ever one answer.

The EZ LYNK AUTO AGENT DPF Delete Tune for 2016-2019 is $899.00.

EZ LYNK AUTO AGENT DPF Delete Tune | Lifetime Support Pack | Ford 2008-2022

Powerstroke owners have the widest window here and the most to double-check inside it.

This DPF Delete Tune for Ford Powerstroke is the Lifetime Support Pack with DSP5 tuning for the EZ-Lynk Auto Agent 3.0, and it's compatible with the Auto Agent 2.0 as well.

The behaviour on the truck is the same as the others.

It lets you run your Powerstroke with deleted DPF (Diesel Particulate Filter) and EGR (Exhaust Gas Recirculation) components, with no codes, no regen, and no warning lights.

More than one engine family lives under this listing, so read this line against your own truck rather than the title.

Fitment covers the 2008-2019 Ford Powerstroke F250-F550 and the 2018-2020 Ford 3.0L.

That breadth is why this one carries the widest spread on the page.

Pricing on the Powerstroke pack runs $899.00 to $1,425.00.

Order for the Truck, Not the Device

Notice what separates these three listings from each other. Not the device generation, not the feature set, not a good-better-best ladder — the truck. Every one of them loads onto either Auto Agent, so the box you already own never narrows the list down for you.

That trips people up who are used to shopping electronics, where the newer unit unlocks the better product. This is not that. Your device is the delivery method, and the thing being delivered is written for one platform and no other.

Which means the comparison a lot of people run — this listing against that one, feature by feature — is a comparison between two trucks that are not yours. Find your platform, and the shopping is finished.

Reading a Year Range Without Guessing

A year range is a shorthand for a set of trucks, not a promise about yours in particular. Two trucks from the same model year can have different engines under the hood, and the engine is the half of the answer a year on its own never gives you.

So do it in this order: engine first, year second, then the form. Your door jamb and your VIN settle both, and the vehicle info form is where you put them down in writing so the right calibration gets built the first time.

Sitting on an edge year, or looking at a chassis cab, or holding a truck somebody else already modified? That is a phone call, not a guess: (888) 830-2588.

Which Pack Should You Order?

There is no cross-shopping to do here, because these are listed per platform and your platform picks for you. What follows is the short version, one line per truck, so you can stop reading and go order.

Duramax: The 2011 Through 2016 Trucks

The LML years are covered end to end by a single listing.

For a 2011 through 2016 GM 2500–5500 Duramax, order the Duramax pack.

You are also the only reader on this page with a rung above 100hp available, which is worth knowing before you compare this against anything else with five levels on the box.

Titan: The 2016 Through 2019 Trucks

Titan owners have the easiest decision in this guide by some distance.

For a 2016 through 2019 Nissan Titan, the Titan pack is the one to order.

One listing, one price, no spread to interpret. The good news? That means the only thing left to get right is the form.

Powerstroke: 6.7L and 6.4L

Two engine families, one pack, and a listing that covers a lot of ground.

For a 6.7L or 6.4L Powerstroke, the Ford pack is the one to order.

Because the coverage is broad, this is the platform where the year and engine you write on the form do the most work. Get those two right and the rest of the order is the same as everybody else's.

Powerstroke owners also have the widest span of trucks in this guide sitting under a single heading, which is a strength and a trap in equal measure. The strength is that you are unlikely to be shut out. The trap is assuming that because the listing covers a lot of trucks, it will sort your particular one out on its own — it will not, and the form is where you stop that from being a problem.

What Does Setup Day Actually Look Like?

No wrenches, no jack stands, and no gasket you forgot to order. The work is a serial number, a VIN, a form, and a switch — which sounds easy until one of the four is missing and the whole thing stalls. Here is where the time actually goes.

Have the Serial Number in Front of You

Read the serial off the device itself and copy it character by character. A transposed digit points us at a device that is not yours, and you will not find out until the tune does not load.

Do it with the device in your hand, not from a photo on your phone from last summer.

Sort the Switch Before the Tune Lands

Order the rotary switch alongside the pack. It is small, it is cheap, and it is the single component most likely to leave you sitting on four levels you cannot reach.

Nothing else in this order depends on the switch, so there is no reason to wait on it. Buy it early and it is already in the drawer when you need it.

Before You Flash It

Two things to sort before the tune goes near the truck.

We suggest that you have ALL codes cleared before reprogramming your ECM with our tuners.^[10]

If the codes you have are not related to the emission system, you must get your truck fixed and clear the codes prior to programming and flashing the ECM.^[10]

Then the power supply, which is the one people skip.

Connect the truck to a battery tender or charger while the flash is running.^[4]

If the vehicle shuts off or dies while it is being programmed, the PCM may become unusable.^[4]

Where People Actually Lose Time

Almost none of the lost time on these orders is technical. It is a form sitting unanswered in an inbox for four days, a modification left off the list because it felt too small to mention, or a year written down from memory instead of read off the truck.

Every one of those is free to avoid and expensive to fix afterwards. Answer the email the day it lands, over-share on the modification list, and read your own VIN rather than trusting what you think you remember.

Keep a Copy of What You Sent

Write down what went on the form and keep it somewhere you will find it again — the serial, the VIN, the modification list as you described it, and the date you sent it back.

A Silverado HD owner is asked to record the date, the odometer reading, who performed the service, and the type of services performed after each scheduled service.^[11]

Same habit, different paperwork.

It takes a minute now. Twelve months and two more modifications later, when you are trying to remember what the truck looked like the day this was built, that minute is the difference between answering a question in ten seconds and taking the intake off to go and read a part number.

Photograph the device with the serial visible while you are at it. Nobody has ever regretted having that photo, and plenty of people have gone hunting for a label under a seat because they did not take it.
