He's a buddy of mine. He's got it hooked to his obdii port all of the time so he can shift it on the fly (feature with the tridog). He went to turn it down tonight and none of the functions work. I said well lets disconnect the batteries and it's back to stock now. This isn't the first bullydog I've heard of doing this so he's going to take it back to the local diesel shop he bought it at. I'm trying to get him to buy the SCT of my 6.0.....You guys need to explain to him what a great thing it is to be SCT tuned....or brought into the light as I like to say!!
