I have a DashBoss forsale, used only a couple times, works awesome. Comes in original box with fuel pressure sender and adapter for a 6.0. Also have the quick connect for the fuel pressure sender. $150 shipped.
Last bump... $100 shipped. Works awesome.... Only selling because I broke my iPad mini and gauges is all I used it for. So I am replacing it with a dash Daq xl, And my cell is a company phone and can't put apps on it. Please google dash boss for more info, this is a great deal for someone looking for gauges. It costs twice as much new Without the fuel pressure sender.
