I got an SCT tuner (canned no custom tunes) for Christmas, I haven't loaded anything because I don't have gauges and hadn't even given a tuner a second thought. Should I keep it and use it or should I swap it out for something else, buy custom tunes, or? Power hasn't really been a disappointment and after my experiences with my old 6.0 I'm all about longevity over power these days!

 

Keep it. Even if you decide not to run the performance programs the scan tool works pretty well.
