For the X4 or Livewire - if you add that upgrade to prioritize the order, you can go ahead and submit your tune form right after purchase so we can build the tunes right away for you and load them onto that device before it ships out. Otherwise, you'll submit your tune form once you have the tuner in hand. From there the normal turnaround time is 3 business days to have them back from us in your e-mail.
