Hi so I am Fairly new to the diesel world so this might seem like a dumb question. I just bought a 2003 dodge cummins with a smarty with tnt-r software. I was wondering if I wanted to get an edge instead do I have to uninstall the smarty software on the truck and how do I do that or how does that work? Thanks

 

At one time people stacked them, I would not run them like that.
The smarty is a better programer for your truck, why would want to
change to a edge? Plug smarty back in and uninstall.
