  1. Egr disable tune?

    6.4L Performance Parts Discussion
    So I was told that unplugging the EGR and using my SCT TO disable the engine code wont really "DISABLE" IT??? IT WILL STILL CYCLE. can someone help me on this. I was told to get a custom tune from SCT to disable the EGR, my question is, can I download this tune? or what? how do I go about doing...
