I have the OG Trail Dash and I like it... I do not love it. It is nice for all the bells and whistles, maintenance monitoring, all of the additional gauges, locking the diffs in 4 hi. In my opinion, if you are getting one for the POWER(!!!), you are going to be disappointed. Besides the shift point changes and changes to the skinny pedal I never thought to myself "holy $hit! this is amazing!!!" I have an 09 JKUR sitting on 33s, on the mileage tune the best I seem to get is 18... on the 87 tune I am around 16.8 to 17.4, and I drive like a grandma... Just my 2 pennies...
