Yea, not too sure if this is the right section. But, Its a matter of opinion I guess. I love mine, and have used it to load my tunes. I've also checked many of codes for people with it. The latest one being Jon(focusin).
let's just say you add a few bolt-ons and want the maximum benefit from your new mods, then absolutely. In my case the Ford X3 power tuner (SCT) was programmed by DynoSpeed Racing (on a dyno) here in Memphis and I love the fact that I not only benefit from my mods, but I get the most out of them + you can check any CEL's....JMHO
