Hey all I have 15 Ram with mm3 tuner. My question is I want to delete my egr. Do I have to due something with the tuner so I don’t get codes? I have the kit but hesitant about putting it on. I still don’t fully understand this tuner.

 

Since it is illegal to modify emission control equipment on a vehicle that had it installed at the factory, I wonder why you would advertise to the EPA by posting here that you are planning to do that.
