I didn't want to hijack the other thread on the OP looking to get his first diesel. I bought my first ('14 Ram Mega 4x4) diesel in December and love it. I do see alot of posts about deleting this and that on diesels... I'm a long time very experienced gas vehicle person (nut & bolt rebuilds), but new to diesel. In the gas world you still have folks that recommend against converting a carb vehicle to Fuel Injection for all the reasons one might come up with, which all really end up being about the talking head not understanding Fuel Injection, and being much easier to throw a rock, than learn something new.

My questions are not about performance, I get various modifications and deletes when looking to increase performance. For the average owner (not hauling a 12k trailer weekly, etc) and for say model year 2012 and above, not Mfr specific (trying to learn something about diesels, not why a PS is better than my Cummins) what and why do you recommend deleting something for general driveability and maybe a mileage increase? I'm really happy with my 370HP-800 ft lbs torque and want to understand why I should change the system my engine mfr designed?

Thanks,
Charlie

Look up EGR cooler and what it does. Once you understand what it does it will anwser why it kills engines, thus why people want it gone.

Also look into clogged DPF. That was really what was killing the 6.4 PSD. The problem with the DPF is that whenever the truck goes to "clean" it, it can never completely clean the filter so over time the filter will get clogged. Also from what I've been told by a few people that a combination of the emission systems are bad for the turbos.

They systems people are talking about deleting have nothing to do with making the truck produce the power it does or how it runs. They are simply add ons forced by the govt to reduce emissions. They cause problems with the truck, higher egt's which will shorten turbo life and the egr system puts crud out of the exhaust back into the motor, not a huge issue with gas motors, but when burning something sooty like diesel its an issue.

The trucks that run urea have far fewer issues with the DPF and tend to get better mileage than the previous versions that just had DPF. In your comparison of only 2014 and up models I believe they all have urea.

I have the infamous f350 7.3. I love it and have not done anything to the motor or components. Would any of you powerstroke lovers suggest that I do this to my truck?

I an currently looking to tune and delete the cat and DPF on my F250 6.4L. The people I know that have done this state more power, if you wanted it (you can add anything from 0-350hp with the right tune and CAI) and better MPG.If you choose to go this route do your research and be prepared to spend some $$$$.

Your truck is pre emissions, you got nothing to worry about.

Also if you plan to add power also instead of just deleting the emissions equipment you will need to do something with your transmission if you have an auto. If you don't budget enough for a new one a couple thousand miles down the road.

When that DPF fails get rid of all the emissions crap my buddy's 6.4 came alive!

Here's a good link, I ripped mine out and had an oiler cooler put in. Coolant filter should be in soon, upgraded my down pipe the other day and repaired the y pipe you can see the EGR is gone!
