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.

 

I would use one or the other. Using both is just asking for problems.

To much power or what. Or would there be to much fuel.

 

too much messing with the computer and fueling and timing i'd assume.

might get some better responses if you post this in the 08 section

 

Can you move this thread to the 08 section.

 

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.
