Cummins Delete Tunes

The tuner came in a padded envelope. The pipe came on a pallet. Both are sitting in your garage right now, the truck is still stock, and you are one decision away from either a clean Saturday or a very long one.

Sound familiar? That decision is the order. It's an easy one to get backwards.

The hardware is the part that looks like real work. Boxes get opened, sockets come out, and the file that should have gone on first is still sitting on a laptop.

We get it. Nobody gets into a diesel truck for the screen time. Wrenching is fun and flashing a file is not. But the file is the part that tells the truck what to expect, and the sequence costs you nothing to get right.

So let's break it down, in the order the job actually happens.

In What Order Do the Tune and the Hard Parts Go On?

The delete tuner goes on first, always. Having the DPF&CAT and EGR kit off your truck without the delete will trigger codes on your truck. You want to be loading the tunes without any codes present. After installing the tuner, you can start removing the hard parts.

Why the tuner goes on a complete truck

Think of the stock truck as the tune's reference point. Every sensor the ECM expects is still reporting and nothing is unplugged. The flash lands on a system that makes sense to it.

The delete tuner seems to work better if everything is connected and in place. That is the whole reason the order exists.

Now flip it. If the tuner throws an error and everything is already off the truck, you are down a truck until the issue is fixed. No exhaust, no EGR, and nothing to bolt back on in an afternoon.

That stops being a Saturday problem in a hurry. Which would you rather be holding when something goes sideways, a truck you can still drive onto the lift or a pile of parts?

What a truck with no codes buys you at flash time

A clean slate is the cheapest tool in this job. Nothing stored, nothing pending, nothing hanging over from a sensor you already pulled. The flash writes onto that.

Start throwing codes before the file is loaded and you are troubleshooting two things at once. Is it the tune, or is it the hardware? With both variables moving you cannot tell, and that is where whole weekends go.

Ten minutes of sequencing beats an hour of guessing.

The order the wrench work follows afterwards

With the file on, the wrench work is the easy half. Pipe or EGR first is your call. Starting with the exhaust makes sense if the truck is already in the air.

Work one system at a time. Keep every part you pull until the truck has run and the dash has stayed dark. Boxes labeled, bolts in a tray, nothing rolling under the toolbox.

Take the photos as you go. You're not scrambling at the parts store mid-install that way. Ten minutes on the floor beats an hour on your back.

Which Delete Tune Is Written for Your Truck?

The EZ LYNK AUTO AGENT DPF Delete Tune is listed for the 2016, 2017, 2018 and 2019 Nissan Titan 5.0L. 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. The EZ LYNK AUTO AGENT DPF Delete Tune sells for $899.00.

Reading your model year and engine off the truck

Two things decide this: the model year and what is under the hood. Your door jamb sticker has the year and the VIN has the rest.

Write both down before you go anywhere near a listing. Guessing from the badge is how people end up with a file that won't load.

Where this fitment list stops

The list stops where it stops, and that is the useful part. Four model years, one engine listing.

Outside those, this tune isn't the one for your truck, and no workaround or different device changes that. It sounds blunt, but it saves you a return and a week of downtime.

Matching the tune to the device you already own

The tune has to land on hardware it knows. Both current Auto Agent versions are covered, which is what the fitment row below is telling you.

If you already run one of them, you're set. If you don't own a device yet, that is the first thing to sort out, because a file has nothing to load onto without it.

What Does the EZ LYNK Tune Load Onto Your Device?

The EZ LYNK AUTO AGENT DPF Delete Tune is written for the Nissan Titan. This is a tune pack for owners who already have an EZ-Lynk device. Lifetime support is a tune-retention entitlement, not a support entitlement. The tunes stay on the customer's profile for life, and support is delivered through the EZ Lynk app regardless of tier.

What you need to own before this is useful

The device is the hardware and the tune is the file. One is a box, the other is a download.

If you don't already own the box, this listing on its own won't get your truck running deleted. That is the single most common mix-up we sort out on the phone, and it is worth thirty seconds of checking.

What the post-purchase form asks for

After you buy, we email a form to collect your tuner serial number, VIN, and any modification details — your order doesn't process until we get it back, so don't sit on it.

Have the serial and the VIN ready and the whole thing takes two minutes. Injectors, turbo, anything already done to the truck goes on that form too.

What the lifetime tier actually retains, and for how long

Lifetime is the word that trips people up, so let's be plain about it. It is not a promise of unlimited hand-holding.

What it means is that the tunes stay attached to your profile and do not expire. Support itself comes through the app, the same way it does for every tier. So the tier buys you retention.

What Do the Five CSP5 Power Levels Give You?

The EZ LYNK AUTO AGENT DPF Delete Tune covers the Nissan Titan. 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). The five levels run 20hp, 40hp, 60hp, 80hp, and 100hp […].

What switching on the fly means in practice

Five files, one switch, no laptop. That is the practical difference between a CSP5 setup and a single-file tune.

You are not stopping the session and re-flashing to change the truck's attitude, you turn a knob. Between rounds at an event that matters. On a dyno pull it matters more.

Sourcing the rotary switch separately

The switch is not in the box. Order it alongside the tune so you're not waiting on a knob to use levels you already paid for.

It's a small part and an easy one to forget, and forgetting it means you run whatever level was loaded last until it shows up. Don't be that guy.

Picking a level for the way you use the truck

Levels are not a ladder you have to climb. Pick the one that suits the day.

Sled pull or a dyno session, go big. Trail work where throttle control matters more than peak power, stay low and keep the truck predictable. The switch means you never have to choose once and live with it.

What Does the DPF and CAT Delete Pipe Replace?

The DPF/CAT delete pipe isn't a full exhaust system. The delete pipe is the same diameter of your factory exhaust system. The front end of the delete pipe connects to your down-pipe and the tail end of the delete pipe connects to the tail pipe, just before the bend over the rear axle.

In the 6.7-liter Dodge Ram Heavy Duty exhaust system, reducing particulate matter is achieved through a self-cleaning Diesel Particulate Filter (DPF).^[1]

Finding both joints before the truck goes up

A lot of guys picture a delete pipe as a whole new exhaust. It isn't.

Here's the thing, it's a section, and the two ends of that section are the only places you have to touch. Get under the truck with a light before you lift it and find them both. Front joint at the down-pipe, rear joint just ahead of where the pipe bends over the axle.

Mark them with a paint pen and the job goes from a hunt to a swap.

Where pickup instructions stop applying

These instruction sets will still sort of work on the Cab&Chassis models, but will require minor modifications. Translate that: the pictures will look close, the hangers will not always line up, and you may be making a bracket.

If your truck wears a flatbed or a service body, budget the extra hour up front. Nobody likes finding that out on their back.

Measuring for bed length before any cutting

Bed length is the other variable. Depending on your truck bed, you may need to cut your pipe to modify your pipe length for fitment.

So measure, then measure again, then cut. A pipe you cut short is scrap and a pipe you cut long is a ten-minute fix.

What Does the EGR Side of the Job Involve?

EGR delete instructions are published for the 2007-2009 Ram Cummins. EGR delete instructions are published for the 2010-2012 Ram Cummins. The first thing you should do is verify you have all the parts. You do not have to delete the physical egr. The pipe has to be removed.

Laying the kit out and checking it against the photos

Empty the box onto a bench before you touch a wrench. Your parts may look slightly different depending on the version you got.

So match by function, not by looks, because a gasket is a gasket even if yours is a different colour. Anything missing, you want to know now and not at hour three.

Which generation's instruction set to follow

Follow the set written for your generation, not the one that looks closest. There are no exact EGR videos for the 2007-2009 cummins models.

So on those trucks you read carefully and work slower. The written steps still hold. The video just won't hold your hand through them.

What has to come off versus what only unplugs

This is the part guys get wrong in both directions. Some of it unbolts and some of it just unplugs, and the difference decides how long the job takes.

Sensors come out. The pipe does not stay. Work the pipe while the truck is still cold, because everything about that job is easier before the manifold has been up to temperature.

Why Would Codes Still Show After You Flash?

If you are using a 2018+ model, make sure that your bypass cable is connected during the re-flash process. Have a battery charger connected and your batteries fully charged during installation. It is also possible that the error codes are caused by your sensors still being in place.

Power and cabling before you start the flash

Power is the cheapest failure to prevent. A flash pulls the batteries down over a long session, and a truck that browns out halfway through a write is a truck with half a file on it.

Put a charger on it. Then check the cable. On the newer trucks the bypass cable is the piece people leave in the bag.

When a second flash is the whole fix

Before you start pulling the truck apart, try it again. Sometimes, the first download may not take properly, and a simple re-flash may solve the issue.

That is not an escalation, it is step one. Ten minutes spent there can save you an afternoon.

The sensors and the valve that have to stay unplugged

If the flash took and the codes are still there, look at what is still bolted on. Ensure that your air intake throttle valve is also disconnected as it needs to remain disconnected indefinitely.

Indefinitely means what it sounds like, and it does not get plugged back in later. Walk the harness once with the instructions in your hand and tick each one off.

Which Cummins Engine Is Under Your Hood?

Cummins engines have been an option in RAM pickups since 1989.^[5] The latest generation Cummins 6.7L Turbo Diesel is a heavy-duty pickup engine.^[4] For RAM 2500 and 3500 equipped with a 68RFE Auto, horsepower and torque have increased to 370 hp and 850 lb-ft.^[3] Nearly 70% of all Ram 2500 and 3500 Heavy Duty pickup owners choose the Cummins Turbo Diesel as their powertrain of choice.^[2]

Placing your truck in the model-year run

Your engine and your transmission decide everything downstream, so start there. Chrysler initially launched the RAM in 1981.^[5]

The partnership with RAM truck started with the Cummins 5.9L Turbo Diesel in model year 1989.^[3] Cummins and Chrysler officials recognized the mutual benefit of incorporating the new Cummins B-series engine into the RAM.^[5]

That same badge now covers a lot of very different trucks. Knowing which one is yours is half the battle.

Pickup ratings against chassis cab ratings

Pickup numbers and chassis cab numbers are not the same numbers. The 6.7-liter Cummins Standard-Output Turbo Diesel produces 370 horsepower and 850 lb.-ft. of torque in the Ram 2500 and 3500.^[6] The high-output engine makes 420 hp and 1,075 lb-ft of torque.^[3]

The high-output rating is offered exclusively in the RAM 3500 equipped with the Aisin transmission option.^[3] So if your door sticker doesn't say 3500 with the Aisin, that is not your number.

In 2019, RAM 3500, 4500 and 5500 Chassis Cab models equipped with an Aisin automatic saw horsepower and torque increase to 360 hp and 800 lb-ft.^[7] The 2019 model year introduced HD pickup buyers to 1000 lb-ft of torque for the first time ever.^[2]

Different truck, different transmission, different number.

Writing down your year, engine and transmission before you shop

Three things go on the note in your phone: model year, engine, transmission. That is the whole set.

The latest generation Cummins 6.7L Turbo Diesel is built to deliver quietness, cold-weather reliability and serviceability.^[4] Those traits are also the first thing a bad parts match takes away.

Write the three down once and you never guess again.

How Does a Diesel Engine Make Its Power?

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.^[10] In a common rail setup, diesel fuel is stored in a high-pressure rail that supplies fuel to each injector independently.^[9] Variable Geometry Turbochargers (VGT) work by varying the exhaust passage area before the exhaust gas entry into the turbine wheel.^[8]

From combustion to crankshaft

Start here, because everything above it is just detail. To operate effectively and safely, the engine must continuously deliver air, fuel and lubrication to the cylinders.^[10]

Air in, fuel in, pressure up, piston down. That is the loop, and it has not changed much in a very long time.

Rudolf Diesel built his first well-known prototype of the high-compression engine in 1897.^[10] Same idea, better metal.

What the common rail changed about injection

Common rail injectors deliver precise amounts of diesel fuel to the combustion chambers.^[9] Common rail pressure stays constant and consistent, allowing precise control over fuel injection timing and quantity.^[9]

That control is the reason a tune can exist at all. The common rail injectors operate in conjunction with other fuel system components, such as fuel pumps, fuel lines, and filters, ensuring a clean and efficient fuel supply.^[9]

So a clean fuel system is not optional housekeeping. It is the thing your file is writing to.

Single, series, and parallel turbo arrangements

Some engines use a single turbocharger, while others use more than one turbocharger arranged in series or parallel configurations.^[8] The primary types include Fixed Geometry, Wastegate and Variable Geometry Turbochargers.^[8]

The variable one is the interesting one, and varying that passage area is the whole trick. That increases the pressure and velocity of the exhaust gas, which then boosts pressure and airflow to the engine as needed.^[8]

VGTs offer versatile optimization across engine speeds and loads, aiding engine braking, exhaust gas recirculation and thermal management.^[8] In plain terms, it is the part that decides how the truck feels off idle.

Is the EZ LYNK Tune the Right Buy for Your Titan?

For a 2016, 2017, 2018 or 2019 Nissan Titan 5.0L, the EZ LYNK AUTO AGENT DPF Delete Tune is the tune to buy. The EZ LYNK AUTO AGENT DPF Delete Tune is currently listed and orderable. Owners outside that recorded fitment need a tune written for their own truck.

The truck this verdict is for

Four model years, one engine listing, one tune. If that is your truck, the decision is already made and you're just picking a delivery date.

Everything above about install order, the pipe and the EGR side still applies, because those parts of the job don't care which file you run.

Who should not buy this tune

If your Titan sits outside those four years, this isn't your file. If you're on a Cummins, same answer, because that is a different engine and a different tune entirely.

And if you don't own an EZ-Lynk device yet, sort that before anything else. Saying who a part isn't for is the honest half of a buyer's guide.

What to have ready before you order

Have three things in front of you: the model year, the VIN, and the serial number off your device. That's the whole checklist.

Not sure which listing matches your truck, or whether a mod you already ran changes anything? Call (888) 830-2588 and someone will read the fitment with you first.
