Doc and Snubby,
Yes you can use your gauges, but you still need to get the Attitude to get all the features of the Juice. Without the Attitue you get less HP and none of the safety features etc. We have directed other folks to get the overhead Attiude mount that goes above your windshield rear view mirror, that way it doesn't interefere with your A pillar mounted gauges, doubles up some gauge functions, but the Attitude has so many different things that it can display I am sure you'll find something that interests you for it's displays.
