I am delighted with my latest Superchips Flashpaq Tuner, this is my 3rd flashpaq tuner from Auto anything. If you have ever hesitated to purchase one of these tuners for fear of the installation process, hesitate NO longer, if i can do it ANYONE can. I have nothing but good things to say about Superchips and AutoAnything, I have and will continue to highly recommend both of these quality companies!
