Hello all-

I'm going to order the tuner/intake combo. I was wondering what is the difference between the two. I do know the X3 is the older model and they are tying to replace it with the SF3. From my understanding the x3 has more tuning options

1) Does the SF3 enable for custom tunes?
2) Which one is truly better?

Thanks everyone

 

The X3 and the SF3 are identical units. The one and only difference is the SF3 holds "canned" pre-loaded tunes in addition to Custom tunes and the current X3 only holds Custom tunes. The older model X3's are actually what the SF3's are now.

 

Yup, that pretty much sums it up.
