The Mads Smarty Junior Tuner for the 2003-2007 5.9L Dodge Cummins is geared toward the customer who is looking to add power that is safe and reliable for both the engine and the transmission and improve gas mileage. In fact, the main concern during the development of the performance software was to ensure the lowest EGT's and smoke levels possible.

Even when used at the highest horsepower level, typical exhaust gas temperatures are on average 200 degrees F cooler than with stock software! Under normal driving conditions Smarty junior can be used without the need for gauges! Even towing up to GCWR.
