The Titan XD with the new 5.0L Cummins is Nissan’s answer to the 1/2 ton diesel truck market, and from initial impressions they seem to have created a great new combination with this truck. The Titan XD is basically a 1/2 ton truck with the engine of a 3/4 ton truck, which really makes it fall into a class of it’s own.
Considering it puts out an impressive 310HP and 555 ft. lb of torque in a less than 8,000 pound truck, the XD sure seems to be punching well above it’s weight class.
All New Powerplant
At first glance, you’ll notice some very impressive materials and packaging used on this engine to make it as lightweight, compact, and powerful as possible.
The construction of the 5.0L is nothing short of high tech, with Cummins opting to use metal technologies like CGI (Compacted Graphite Iron) to make the block thinner and more lightweight while staying as strong as possible. Aluminum was used to cast the heads which heavily contributes to the 5.0L being much much lighter than any of the older diesel v8’s that we are used to.
The packaging was designed for a small footprint, using tricks such as tucking the turbos deep into the valley pan area, with the intake manifold just about being molded right around them.
Clean and Quiet
A lot of emphasis was put into making sure that the 5.0L Cummins V8 would put quietness and cleanliness at the forefront of their design.
The Bosch piezo injector system has the ability to fire five times during each combustion event, keeping the pistons from slapping the walls and creating unwanted noise. Cummins even took into consideration the timing of the fuel pump, and by running the Bosch CP4.2 off of the timing chain, they were able to set it with precision to sequence the combustion cycle.
And of course, because of modern diesel regulations, the 5.0 has all of the usual emissions equipment that you would find on any new truck.
The Problems
Just like every other modern diesel engine, there are always trade-offs. Namely the DPF, SCR and EGR systems. They’re what really hold this engine back from it’s full MPG and HP potential, while contributing to future failures.
Don’t get me wrong, when these systems are operating properly they do help to greatly reduce emissions and are generally a good thing. They’re also a requirement if you live in a country with regulations on diesel pollution. While they are good systems for reducing tailpipe emissions, they definitely have the trade-off of collateral damage that they can cause that becomes a concern for the longevity of your truck’s engine.
Fortunately, there are still options for those of us who don’t live in the United States, or who only use our trucks off-road.
How to delete the Titan XD
There are only a few parts that you will need to delete your 5.0 Cummins; a tuner, an exhaust, and a some way to block or turn off the factory EGR system. All of these parts together are what most will call a full delete kit.
We’ll start with the most important part first, the tuner. You won’t be able to run a deleted truck properly without it, so it is definitely a must have in order for everything to work.

EGR Delete Options
Unfortunately, there really aren’t any readily available delete kit options for physically blocking off the EGR system on the 5.0L Cummins, instead most everyone simply turns off the EGR function with the tune.
As someone who really values a clean engine bay free of unnecessary junk, I would like to see the market respond with some more options for EGR block off plates for this truck.
Stay tuned here for updates, we will make sure to post any new delete kit options as they become available.

Is the tune plug and play?
Hi Jon,
Yes the tuner is plug and play for this application.
Is the tuner delete selectable, meaning can I insrall it, disable the egr, and leave dpf enabled. Later remove the dpf and then select delete in the programmer? Allowing me to delete things in steps?
Hey Mike,
I don’t recommend doing the deletes piece by piece because if your EGR is shut off that causes extra soot which is just going to clog up the DPF even faster.
Why is there a big prize difference on the purchase of the ez link ? I seen it for $499 and also for $1299.
The difference is that the more expensive version comes with a custom tune. The cheaper version is just the tuner itself with no custom tune included.
One is just the tuner and the other is the ezlynk auto agent I have the auto agent and it’s worth the price difference. With auto agent they will send you the tunes you need anytime and anyplace as long as you own the trucking. They will help you with any codes you may have. Hope that helps
Can you send me the name of anyone who has a lot of experience doing a delete on a 2016 Titan PR please I am tired of the issues with the engine I have had.. I have a engine code of P1C54 now. I do have an extended warranty, not really sure that will cover it anyway. But there is only one Diesel Mech for Nissan in all of Louisville, the other shops have told me they have a non compete contract with Nissan not to do any work on the Titans with Cummins engines.. I never heard of such things.. How can an owner get any fixes done and what good is an extended warranty then! Really pisses me off..
Hi Mark,
I am not aware of anyone in the Louisville area that could help with that. Good luck with your search.
If I get the race pipe. 4″ Delete Exhaust for 16-17 Nissan Titan XD Cummins. What attaches to the end of it to go over the axle and is it an exact match to the downpipe?
Hey Mark, the exhaust listed right now replaces the downpipe and goes out over the axle.
Thanks my friend, I have a 2016 Titan XD with the Cummins 5.0L and have been living hell since I bought this vehicle. The truck has remained in the garage for 3 months in 1 and a half years. All the components of the anti-pollution system broke one after the other. Now that the guarantees are finished I send it to the garage for the DELETE. I am looking much more for reliability than performance. I hope everything will be for the best otherwise I will change trucks. I live in northern Quebec, here the temperature in winter regularly reaches -40 so the DEF system is really not suited to my needs
I have a 2017 Nissan Titan pro XX and I deleted mine and put a new cold air intake and a ezlynk tuner on it and of course I straight piped it. No more problems and wow did it wake my truck up. Did the up grades a year ago and haven’t regret it yet.
