OK I almost made a dumb mistake before I got educated with a Smarty. I had ordered a superchips flashpaq but I kept hearing about this Smarty. I have decided to order the Smarty and resell the superchips. I just have a couple of questions. 1. I have an Edge EZ already on the truck, will they be compatable or do I need to ditch the EZ? 2. When I upload the smarty do I need to unhook the EZ first (if they are compatable of course)? Finally, is anyone looking for a Superchips Flashpaq 3805 unopened and in the box? Hehe. Oh well that was before I got educated by a Smarty.
