6.7 Cummins EGR Delete Without a Tuner: What the Kit Does, and What It Still Needs

Can You Run a 6.7 Cummins EGR Delete Without a Tuner?

The EGR Delete Kit is made for the Dodge Ram with the Cummins 6.7L. Nearly 70% of all Ram 2500 and 3500 Heavy Duty pickup owners choose the Cummins Turbo Diesel as their powertrain of choice.^[1] The hardware and the calibration are separate line items on the same job. Plan for both before the parts arrive.

So the honest answer is no. Let's break it down, because these two halves get mixed up constantly and the mix-up costs people a weekend. One half is metal you can hold. The other half is software, and it is the half that keeps your dash dark.

What the hardware actually does on its own

Your intake stops eating its own exhaust. The EGR Delete Kit for 2010–2024 Ram 6.7 Cummins permanently removes the Exhaust Gas Recirculation (EGR) system, stopping the soot buildup, valve clogging, and heat that make the EGR a common failure point on these trucks. That is the hardware side, start to finish. The latest generation Cummins 6.7L Turbo Diesel is a heavy-duty pickup engine that delivers the power, towing performance, quietness, cold-weather reliability, and serviceability that truck owners depend on every day.^[2]

What it does not do is change how the ECM reads the engine. The computer still goes looking for a system that is no longer bolted to your motor. That is the gap the calibration closes.

Why the tune is a separate decision from the kit

Here's the thing — a kit on its own is not a delete. Pulling the head unit out of the dash and leaving the harness plugged in is the same move: the hole is real, and the wiring still wants something on the other end.

Sort the calibration before the box lands on your porch, not after. Guys who get the hardware first and think about the tune later are the ones sending us photos of a truck on jack stands late on a Friday.

Who should stop reading here

If a delete tune is not in your plan, this kit is not the right part for your truck. That is not us hedging. It is just the shape of the job.

We get it, nobody enjoys adding a second line to the build sheet. Plan for it anyway and everything below will land a lot cleaner.

Which Ram 6.7L Cummins Does This EGR Delete Kit Fit?

Model year and engine family decide it. The EGR Delete Kit covers Dodge Ram trucks with the Cummins 6.7L. It fits 2010 through 2024 Ram 2500, 3500, 4500, and 5500 with the 6.7L Cummins (Pick-Up 2010–2024, Cab & Chassis 2013–2024) and does not fit 5.9L Cummins engines. The 6.7-liter engine features a 107mm bore by 124mm stroke, versus a 102mm bore by 120mm stroke for the 5.9-liter engine.^[3]

Reading the model year and engine off your own truck

Badges lie. Castings do not. Two trucks can wear the same tailgate letters and land on opposite sides of this list, so go by the engine family and the year on the door jamb before anything else.

The 6.7-liter Cummins Standard-Output Turbo Diesel produces 370 horsepower and 850 lb.-ft. of torque in the Ram 2500 and 3500.^[5] That is the number to know before you start comparing parts. The Ram Heavy Duty is the most powerful, most capable pickup in the segment with a towing capacity of 35,100 pounds and a payload capacity of 7,680 pounds.^[4]

Pick-Up coverage versus Cab and Chassis coverage

The two windows are not the same length, and that trips people up. A pickup owner gets the full run. A Cab and Chassis owner joins it later.

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.^[6] Different truck, different rating, same engine family — and the same fitment question either way.

Work out which side of that split you are on before anything else. It is a two-second check on the door jamb and it decides everything after it. Get it wrong and you are the guy holding the right kit for somebody else's truck.

Where this fitment list stops

The 5.9 is the hard edge. Those two engines do not share a bore or a stroke, and the hardware follows the castings. Check the engine family first and the year second, and you will never be the guy standing over an open box with the wrong part in it.

Why Does the EGR System Clog on These Trucks?

The EGR system reroutes hot exhaust gases back into your intake manifold, and those gases carry soot. Over thousands of miles that soot coats the intake and clogs the EGR valve. The EGR system is water cooled, with the air reintroduced into the intake system, keeping turbo and intercooler components clean.^[3]

Where the soot comes from and where it ends up

Soot is not a defect. It is what a diesel makes, every stroke, every mile, and the system was designed to send some of it back around on purpose.

The trouble is that the intake tract was never meant to be a chimney. Push hot, dirty gas through a cool aluminum passage often enough and it leaves a deposit behind, the same way a wood stove pipe glazes over across one winter. Nothing failed. It just filled up.

What the cooler was designed to do

The cooler is there to take the edge off that gas before it goes back in. On paper it is elegant engineering, and on a low-hour truck it does exactly what it was drawn to do.

Add years and heat cycles and the passages that once carried clean gas start carrying deposit instead. That is the moment the part protecting your turbo turns into the part your truck is fighting.

The signs owners notice first

You feel it before you see it. Throttle that used to be crisp goes lazy off idle, and the truck feels like it is breathing through a straw.

Then the light shows up on the dash. By that point the deposit has been building for a very long time, and cleaning it out is a temporary win at best — you are treating a symptom that will come back on its own schedule.

Guys chase it in the wrong order, too. New filters, fresh fluids, an afternoon with a scan tool, and the truck still feels flat off idle. None of that reaches a passage packed with deposit, which is why the same complaint keeps coming back around.

What Does a Failing EGR System Actually Cost You?

A failing EGR system can lead to overheating, head gasket damage, poor fuel economy, limp mode, and expensive repairs, often over $2,000 if left unresolved. This kit removes the EGR at the source instead of chasing the symptoms. The Cummins 6.7-liter turbo-diesel engine has life-to-major overhaul intervals of 350,000 miles.^[3]

The repair bill nobody budgets for

Ever priced a head gasket job on one of these? Nobody plans for it. It shows up as a coolant smell, a temperature needle that will not settle, or a truck dropping into limp mode between rounds with the trailer already loaded.

The ugly part is the order the bills arrive in. You clean, then you replace, then you find out the heat took something more expensive with it on the way through. Chasing a clogged system one piece at a time is how a few hundred dollars turns into a few thousand, and the truck sits on the lift the whole time.

Budget the honest way. Price the worst outcome rather than the best one, because the parts that let go around a clogged system are never the cheap ones. A truck that spends its weekends working finds the top of that range a lot sooner than a truck that sits.

How a hard-worked truck accelerates the problem

A truck that works for a living ages differently than a garage queen. Severe service, including heavy loading, trailer towing and off-road use, may reduce oil change intervals.^[7]

The EGR side moves in the same direction. More load means more heat, more heat means more deposit, and a competition truck stacks up hours a lot faster than the calendar suggests it should.

What the engine underneath is actually rated for

Here is the part that stings. The long block is rated for far more service life than the system hanging off the side of it, so the thing that fails first is not the expensive thing.

Built like tanks is not marketing on this engine. It is why so many of these trucks are worth fixing properly instead of moving on from, and it is why people delete the EGR rather than rebuild it a third time.

What Comes in the EGR Delete Kit?

You get the complete EGR delete kit, the throttle valve delete, all hardware and gaskets, and a DIY-friendly step-by-step guide. The kit physically blocks off the EGR system so exhaust gases stay where they belong, and it includes a throttle valve delete for increased airflow, quicker turbo spool, and lower EGTs. The EGR Delete Kit includes all hardware and gaskets.

Everything the box carries

That list above is the whole list. No sourcing gaskets separately, no run to the hardware store halfway through the job, no ordering a fastener you did not know you needed. Parts may look slightly different depending on the version you got.

The exact piece count moves with the version, so count what arrived against what the guide shows rather than against a photo you found somewhere. Match the count, not the shape.

Do that on a clean bench with good light. A missing gasket looks exactly like a present one when it is buried in packing material at the back of the garage, and finding out the hard way is how a short job turns into a long one.

What the throttle valve delete adds

This is the half people skip past, and it is the half that changes how the truck feels. Increased airflow and quicker spool are not abstract — they are what your right foot notices first.

Lower EGTs are the quieter benefit. EGT is exhaust gas temperature, and on a truck that lives at high load it is the number that eventually breaks something expensive. Anything that pulls temperature back out of the equation is money in your pocket later.

Checking the kit before you touch a wrench

Ten minutes on the bench beats an hour on your back. Open everything, lay it out, and match it to the guide before a single bolt comes loose.

If something is short, you want to find that out on Friday night. Finding it at noon on Saturday, with the old cooler already off the engine, is a different kind of weekend.

What Should You Expect During Installation?

Install usually takes 3–5 hours with basic hand tools, no welding, and a compatible delete tune is required to prevent codes. The EGR Delete Kit ships with all hardware and gaskets. EGR delete instructions are documented for 2010-2012. EGR delete instructions are documented for 2013-2018. EGR delete instructions are documented for 2019-2021. EGR delete instructions are documented for 2022-2024. Verify you have all the parts first.

The tools the job actually needs

Nothing exotic. A socket set, a good run of extensions, a breaker bar for fasteners that have been cooking for a decade, and penetrating oil sprayed the night before.

Add a drip pan and a handful of zip-top bags for hardware. Labelling as you go is the whole difference between a clean afternoon and an evening spent guessing which bolt came from where.

Lay the tools out before you lay the parts out. Sockets in order, extensions within reach, a light you can move with one hand. Half the frustration in a job like this comes from standing up to go find something, over and over, with your hands already filthy.

Finding the instruction set for your model year

Four brackets, four separate instruction sets. Match your year to its bracket before you start reading, because a sheet written for the wrong bracket will walk you straight into the wrong path.

Not sure which one your truck sits in, or hit something the guide does not cover? Call (888) 830-2588 and we will sort it out with you before you are elbow deep in it.

The order to work in

Read the whole guide first, cover to cover, before you pick up a tool. That sounds obvious and almost nobody actually does it.

Work cold, too. A motor that ran an hour ago will punish you for reaching past the manifold, and rushed hands round off fasteners that would have come out clean.

What to check before the old parts come off

Count first, wrench second. Every part accounted for, every gasket in the pile, the guide open in front of you.

Then check your clock. Give yourself the full window plus a buffer, because the truck is not going anywhere once the old hardware is off the engine.

What Changes on the Truck After the Delete?

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.^[9] Variable Geometry Turbochargers (VGT) work by varying the exhaust passage area before the exhaust gas entry into the turbine wheel.^[8] VGTs offer versatile optimization across engine speeds and loads, aiding engine braking, exhaust gas recirculation and thermal management.^[8]

What the gas path looks like afterwards

Exhaust goes out. That is the whole change, and it is simpler than most people expect once the hardware is off the engine.

Everything after combustion is managing where those gases go, and the delete takes a branch out of the plumbing for good. That is the whole mechanical story, and it is worth knowing before anyone tries to sell you a bigger one.

How the turbocharger sees the change

Your turbo lives on exhaust flow. A VGT is a Variable Geometry Turbocharger, and the short version is that it can change the size of the doorway your exhaust squeezes through.

So anything happening in that passage changes what the turbo has to work with. That is why the exhaust side of this engine gets so much attention on a build, and why a delete is rarely the last thing anyone does to one.

None of that turns the turbo into something it was never built to be. It just means the exhaust side is where the decisions worth making get made on this engine, and it is worth understanding before you start stacking parts on top of each other.

What not to expect

Let's be straight about the ceiling here. Better throttle response is the change owners report, and that is where the honest line sits. This is not a power adder, and nobody should sell it to you as one.

Want the bigger jump? That comes from the calibration side, and it is a separate conversation with a separate budget. The hardware clears the path. The tune decides what walks down it.

Is the EGR Delete Kit Worth $299 to $380?

The EGR Delete Kit starts at $299.00. It tops out at $380.00. Free shipping. Unused kits are returnable within 30 days; once installed, returns are not accepted. It's the best-selling Ram Cummins EGR delete kit. Cummins engines have been an option in RAM pickups since 1989.^[10]

EGR Delete | Dodge 6.7L Cummins Diesel 2010-2024

This is the kit the whole guide has been describing. Check your year and engine against the table above, then decide whether it belongs on your truck.

What the price covers and what it does not

The number on the page is the hardware. The tune is its own line, and pretending otherwise would be doing you a disservice.

Set the kit against what a single cooler job costs and the math stops being much of a debate. That is the honest comparison, and it is the one this decision actually turns on.

The return window and the point of no return

The window is real and the edge is hard. Unused means unused, and once it is on the engine that door is closed behind you.

So do your checking on the bench, not on the truck. Confirm the year, confirm the engine, confirm the chassis, and then start turning wrenches.

Which truck this kit is for

For a 2010 through 2024 Ram with the Cummins 6.7L, this kit is the one to buy. Pick-Up owners have the full window, and Cab and Chassis owners join it later in the run.

If your truck runs the 5.9, this is not your part and no adapter changes that. And if the tune is still an open question, get that answered first — the kit will still be here when you are ready for it.
