I am really curious about this.. are you certain that you can add additional mods later that were not purchased from them and they will update your tune for free?
I'm certain that if you're a Free Tunes for Life member, we'll write you new tunes as long as we can, no matter where you get the parts. If you get a tuner and a custom tune as your first mod, then pick up a CAI from Ebay, all you have to do to get a new tune is give us a call. We'll even write a new tune if you decide you want a different type of tune from your original. Our turnaround time is about 2 business days right now and if you have any questions about your tune, and you can always send me a pm or give our tuning experts a call. We're always happy to help.
