Post Injection

[EverydayDiesel]

Can someone please tell me what the purpose of post injection is?

I cant figure out why this is needed and my instinct tells me to 0 out the table but maybe it has a useful purpose?

Holy moly my friend!
Light reading is an understatement. Is there any disadvantage to 0'ing all post tables?

Thanks to everyone that replied.

On a stock truck (deletes/cold air) i noticed almost no difference. I will see how the mileage is affected.
