H&S Does It Need Help
My buddy has and 08 Dodge Cummins and he was wondering what his truck would do with the smarty stack with it. Would it hurt it by mixing the two together or would it be good running the two together.
They are both downloaders. They are either going to write over each others tunes or you will get an unknown software error on them. So either way you are only going to get the power from one or the other, there is no way to "stack" them.
