I bought the bully dog for my 12 maxima.I definilty have gotten a 10% increase which you can feel.The driving coach program is good for those that want to get more m.p.g.When installing let me save you some aggravation and tell you that you will need to hook up to a charger or other car for the boost for the battery when installing the premium program into your cars ecu.Customer service at bully dog will def. help you if you encounter any problems.Moneytopowergain worth it.
