I just bought a superchips tuner. Has anyone out here had any experience with them. Good or Bad? I was wanting to start playing a little, but didn't have the green to lay down for the edge/juice, would love to have one. I wanted to have tuner and a code reader, and I can clear the codes with this one to if need arises. Would love to hear any feedback from anyone with experience with this particular tuner. For $200 I thought this might be a good introduction to the tuner world.
