| I was in the same boat as you a month ago and ended up going with the edge w/ attitude and love it.I'm not sure about the mileage gain because I can't seem to take it off level 3 and gunning it.I did notice a gain in mileage on the level 1 setting but I got my exhaust at the same time and between the power gain on level 3 and the awesome sound coming out I can't stop unleashing the horses.The gauges are great to have,I know they aren't as accurate as regular gauges but you can monitor up to 4 different things and it's a small easy to install unit.Hope this helps............goodluck.
