I have one gauge in my car. Aeroforce. The wideband feeds into it, a fuel pressure sender kit can send into it, an oil pressure kit could send into it. Beyond that..what could a guy want?

And honestly.. if you are monitoring things, you'd know if pressure was low on either w/o having a sender or gauge for them. You'd see a lack of fuel in the WB and you'd hear the oil pressure drop off and engine check out.
