I like dash mounted gauges, i just didn't want to mess up my dash by putting holes in it or using double stick tape to mount, I also don't like seeing wires across the dash leading into the front defogger vent. I wired my A pillar gauges to my cluster dimmer switch so I can turn them off at night. They stick out a lot less and when ricers/idiots/police come along I just turn them off and stay out of boost. I tried to keep gauges to a minimum too, just oil pressure, boost, and my wideband. My interior isn't flashy at all. I don't even have a radio.
