Intalled easily with juice unit but display unit is a pain to get stuck to dash if you've ever put anything on the dash. There are SOME things it can monitor but you only get to choose between SOME of the things the onboard computer can see. Can't figure out why they wont let you monitor anything the gas version can as well on the diesel. Gas mileage has only increased on freeway and stayed about the same in city. You can definitely feel the difference in mode 3.
