I have an edge ez for a 03-04 cummins I bought it just for some extra power and fuel mileage and got so addicted to the power that I needed more, so I ended up buying a smarty ssr. And now it's just collecting dust I'm asking $275, and ill pay for the shipping! Still works great, it has 4 power settings. U can pm me or send me a text at 573-201-5513. Thank u!
