MADS Smarty S67 Tuner (2007.5-2012 Ram 6.7 Cummins)Smarty. this is a name that has been synonymous with Dodge Cummins for years. It's hard to describe to someone what is different about a Smarty tuner versus "others" until they drive it. Even with having similar power levels to other brands of tuners, Smarty has the leg up on drivability. Think of it this way, while there are many other tuners on the market that make the same power (if not more) than a Smarty, its all in how each GETS to that power.
