A little disappointed in the lack of "tuning options". Apparently for the 2004 Durango with 5.7 Hemi, you are only able to program for 87/92 octane, rev limiter increase of +500 RPM, and change vehicle max speed limiter. I was REALLY hoping for shift point & firmness adjustment. Also noticed that after I'm done programming, I now have a P0000 code that will NOT go away... check engine light is always on, but it's just this single code. :\ Overall, I'm satisfied, but a little disappointed.
