Haha no you're not wasting my time!
I'm in the Air Force and supervise 90 people, so I'm all about getting feedback from as many people as possible, and you seem to be one of the most knowledgeable folks here. I haul my Mustang, boats and campers so definitely getting the tow tune. My SCrew is rated to pull 7500 pounds and I use a lot of that. It's just so hard to pick 3 tunes when I could use 4!
I think I'm going to have to narrow it down to the 89 perf, 89 tow, and 91 perf and switch back to stock to run E85 since, like I said, I mostly use it when I go visit the folks and that's usually once a month. The price point of E85 vs regular in North Dakota isn't quite as good as back home so it's something I can live without for the time being. After driving it for a while if I decide to scrap the 91 perf tune for E85 perf, I'll do that. It's nice having that option! Did I mention I'm really glad I found this site?!
Word of mouth is a powerful tool...
