Good questions, keep em flowing.

It took 3 days for me get my order from Tunableinductions. As long as you want the none painted "stealth" version John has them instock and rdy to fly. I guess the tuner just gets the info uploaded. I imagine it takes like no time at all.
The support from John Demolet and I hear many other tuners such as Bamachips, alterntiave auto, Evolution offer complete support after you buy your tunes. In other words if you add gears, bigger rims etc they will send you a new tune (or tell you how to change it)to reflect those changes. Best thing you can do is call your dealer of choice and flat out ask them what they can do for you. These guys aren't like huge dealers so you get very good customer support and a guy who wants to help.
