Delete your emissions crap. It's deterimental and prone to failure anyway, and it's all based off fear mongering that those darn sooty diesels are terrible for the planet. I've done several newer trucks and all saw power and fuel economy increases, with only minor increases to tailpipe emissions.
There are several tuner options from any of a dozen different manufacturers that allow you to remove the emissions systems without causing any problems or codes. Many market their product for "markets where ULSD is not available" to loophole removing the emissions equipment. Any of the "big 3" domestic manufacturers are covered and there are options out there for the euro diesels as well.
^yup.... the etiquette within the community is NOT to mention names of companies or individuals who script programming to defeat the emissions... keeping that option alive, instead of putting them in harms way where they'll face penalties such as H&S Performance faced.
the emissions equipment on these things is counter intuitive, anyways. It defeats itself... so- let's say it reduces the emissions 25%- but increases economy 25%... where is the advantage? Meanwhile, people with some sense and not into 'rolling coal' (which is idiotic and wasteful) tune with efficiency in mind, and achieve a tail pipe sniff better than OE, and while increasing horse power and torque... How asks you? The marvel of variable geometry sequential turbo technology coupled with piezoelectric injectors playing gate keeper to a silly high rail pressure...
the concepts are simple- sequential variable geometry turbos, one low pressure high volume, the other high pressure lower volume, allow response right off idle- and the piezo injectors can have as many as five distinct injection events per cycle- not forgetting the all important 'pilot' injection... the piston can be chased all the way to the bottom with injection that tapers off volume ensuring it's burned instead of continuing to burn in the exhaust.... this is only possible in a computer controlled and monitored environment... today's diesels are light years ahead yesteryears with mechanical injection and unbalanced fuel to air dumps.
enter the EPA and mandates- many if not ALL engines were retrofitted to meet the requirements... DPF's, DEF's, DFluid, EGR's, ect... because they were 'added', they can be removed... and it happens all the time.
remove those items dealing with exhaust- from the catalysts to the filter to the EGR and it's related equipment, you'll find that these engines are back to being able to run about anything 'diesel'..... but..... the fuel needs to be filtered and 'polished' before the engine consumes it... 500ppm isn't an issue... once you head north of that, though, you can expect that QC is much less, and it needs to be filtered a few times before feeding it to your engine...
about fuel: 15ppm removes sulfur.... yay... but the process also removes lubricants- no yay... this is extremely hard on high pressure pumps that use the stuff to not only pump, but also to lubricate and cool... so even users of 15ppm should be lubricating their fuel... the 500ppm is a lot 'slicker', and not in need of constant treatment. so.. to tidy this up- remove the emissions equipment and run 500ppm exclusively and your engine will last a lot longer and be more reliable.
