Deleting/ gutting and codes?
If I delete or gut the SCR cat, leaving the DEF injector, will it throw codes?
What else Can I do to the exhaust without reflashing the computer. |

That's what I figured. I just fixed my 4d16 (cleaned the metering valve) this emissions crap is just so finicky... ready to delete but not ready to pay $1000 plus yet...
