X15 Bad fuel economy and sluggish power

[Rawze]

First of all, you need to get rid of that garbage-can tuning box that is going to do nothing but cause serious engine harm internally via the horrible injection timing and all the other engine killing settings those idiots are very well known for. -= put the original program back in it that belongs in it from the factory.


NEXT.. someone can do a 100 regens in a row .. and it will not clean that DPF canister the same as removing it (and the DOC unit) and taking them to have it professionally cleaned at an OEM dealers$it for a few hundred bucks.


The engine regen process is only about 2-3% effective at best. It will not, and cannot bring it back to its original state.

To properly clean one back to its original state, it needs to be baked, de-ashed, and then flow-tested on a proper set of machinery. It is recommended to do this about every 2-3 years, and/or about 250k miles or so on them to keep them healthy. Also, be aware that ANY liquid cleaning process it damaging to them over time.. and should be avoided. It washes out the precious metals and weakens them.


As far as saving fuel.. driving it right, driving by your boost gauge and keeping boost limited, etc.. are the most effective things of all. Next, is to do a proper egr-tune-up on it and replace the IMAP sensor, clean out egr piping, etc.etc.etc... once a year to keep the engine healthy, as described here...

Your post also implies that you are likely driving it into the ground with all the power, instead of driving it for better profits and longevity. That is no way to treat your equipment.
