[QUOTE="stanger1, post: 15634358, member: 134171"] I have been wanting to do that kit to my 13, but we only have 91 octane here and was worried that the 91 would not be enough as we are at 1320 above sea level. From what I have read, even the stock Ford tuning is based on 93, so with the 91, I am already down on power. [/QUOTE]
