Anyone here running the SF3? If so, what options did you change and what pre-loaded tune works best for you? I have one and needing some ideas on what to tweak besides tires size and governor lol. Mine is an 02 SCrew 5.4

 

The sf3 will have three tunes in it, 87, 91 and 93 octane. The 87 is designed for primarily for daily driver duty, towing and fuel economy and the 91 and 93 is more performance oriented tunes.

 

And check out www.sctflash.com, product, 3015, the adjustable options tab at bottom. That's everything you can modify yourself within the tune.

 

I was looking for specifics of each tune. I have the 3015 already, just wanted to know what changed between the 3 tunes besides octane
