Our tuners are probably the best bang for the buck mod you will find for your new fusion!
As far as the nitrous, when DONE PROPERLY, it can be plenty safe. This means custom tuning done on a dyno to control the air fuel ratio. Also, the stock plugs are platinum, which dont stand up too well against nitrous. bottom line is, probably not worth the risk unless you have a professional shop that has a LOT of experience with nitrous do it all for you. Even then, you wont want to run a tune made for nitrous when youre not spraying, since it retards the timing, which is good for nitrous, but makes the car sluggish when not spraying.
anyways its a fusion, why you want to race a auto 4 door car, sure its fun to drive, sporty but meh... iam looking at the bobs chip mainly for how people say its much better drive with it, better shifting and so on, sure if it nets me 5-10hp i would be happy with it as well... but NOS.. blah... waste of time imho.
