Def Delete Kit Question - Understanding Its Purpose

[sullybosco]

Hello everyone,

I am currently working with a project where I encountered the "def delete kit" function and was unsure about its purpose.

From my understanding, this function is likely used for removing a kit or collection of items in an application, but I would like to know more about its exact use case and any potential pitfalls to watch out for.

Can anyone explain what this function does specifically, and whether there are any important considerations or best practices for using it?

Any insights would be greatly appreciated.

I'm sort of surprised that tuners are still selling these after the EPA crackdown on diesel tuners that swept up performance car tuners with it. A DEF Delete kit is used to delete the diesel exhaust fluid system from a diesel truck. It would include new exhaust pipes (usually "free flow" i.e. larger and with less muffler), something to remove the computer control of the DEF system, and plugs to close off places where the DEF came from. It removes one of the ways that diesel exhaust is cleaned up. It would at the least be marketed as for "offroad use only", which is apparently no longer being allowed by the EPA.

Looks like he’s not American, so likely that regulations are significantly less.

Stateside, all the EPA did was drive sales underground and make it more expensive which I’m sure was their goal, in part, because less people will pay the higher price.

Ultimately, many of the emissions control devices are desirable to remove because they are said to decrease reliability. I’m highly ignorant regarding DEF systems, but things like EGR valves and PCVs just dirty up otherwise clean intake tracts with a bunch of nasty crap that gunks up valves and decreases octane/knock resistance in many cases which is why everyone deletes them.
