For those about to "knock"......

Serious question about custom tunes. I ordered 91 performance and tow tunes thinking it is the option for maximum performance. Ford on the other hand says 91 octane is definitely the wrong fuel for my truck. I have no clue as what to believe but they swear it can potential do more harm than good. Anyone care to derive an educated response to this? I am like so over learning the hard way! The service tech told me I need to be running 87 octane w/ an occasional booster or top off with 91. In either case, can someone tell me why I was'nt informed prior to ordering my custom tunes? Now I feel I have to have Bill or Cody change them over to 87 custom performance and 87 custom tow. Can a moderator please cue Bill, Corey, or Cody into this and see if they are willing to help me? Also, they said it was a factor in the plugs going bad because the fuel burns too slow. Thanks in advance to anyone kind enough to shed light on this subject.
