Smarty Jr Programmer | Dodge Diesel Tuner

The Smarty Jr Programmer by Mads Electronics is the easiest point of entry to providing your Dodge Diesel truck with superior performance, horsepower and torque. There are two versions of the Smarty Junior. One for the 2003 to 2007 5.9L Dodge Cummins and then one for the 2007 to 2012 6.7L Dodge Cummins. There is no Smarty Jr for the 1998 to 2002 5.9L Cummins. For that you will need the original Smarty Senior programmer, the S-03.
