I talked to them and they suggested a single 87 RV tune but I know a couple of people here have the 91 performance. I live on the front range in Colorado, it will see moderate wheeling and plenty of time on the interstate too going both east to Iowa and to the west coast occasionally.
Thoughts on which tunes I should get would be appreciated!
Unless he's changed things you get 3 tunes with the tuner, so try them out. Honestly, I would recommend 87 performance, for when you want to run regular, 91 or 93 performance for when you want to spend more on higher octane fuel. If you tow, get an 87 tow tune too. It just takes about 2 minutes to change your tune. I've done it while fueling the van many times.
