havent seen that posted yet so i was just wondering, if the edge is gunna be 5 months comming out id like to snatch up a cheap programer to fix my speedo anyway so i can get my full mileage writeoff on my work truck. will the edge have a speedo adjustment option? have previous ones? and if not, will i be able to stack them, like use the edge for performance but p/p for tire adjustment? sorry for all the questions, my last diesel i just slaped in a basic programmer and went with it, this time i wanna do it right.
