I have an SCT SF3 tuner for sale that comes loaded with 3 tunes (3 octanes). The tunes were originally for a 2012 3.5L but I had it on my 2013 3.7L without any issues. You can definitely feel a difference.
This was purchased from morepowertuning.com. I don't remember what I paid but it was more than the $299.99 that they are selling an open box one for now.
It is not married and has at least 1 unlock left. I will need to check how many it has left.
I am looking for $200 or best offer.
I am selling the Ford Edge so I don't need this any longer.
