That is interesting to hear as I have not experienced that. They(Jake) usually gets back to me in under 3 days when they were tuning my stock twins. He helped diagnose that my twins were shot vs. an exterior problem. Very often he would get back to me in 1 day. I am sure it depends on their family life/vacations/how busy they are as I know all the guys have full time jobs and they do this on the side. There are also more employees there now vs. Jake doing it all which is how it was before I believe. When they 'were' PTF Jake was pretty responsive as well, he tuned my old e90 and I never had a complaint about waiting for new map revisions. That being said, I am also never really in a rush and can handle waiting some time as I have a DD.
That all being said I am sure some people have experienced that wait time you are describing with remote tuning and motiv.
One thing that is nice you can reserve them on say a Saturday for remote dyno tuning if you pay $$$ or I believe they will come and do it in person if you pay enough $$$ as well.
One final positive note for Motiv, other than everything I said in my post above, is I think they have been flash tuning(jake) longer than anyone else on this platform by at least a year or two.
I'm still pending a response to my initial request by them that is over a year old The boards are collectively full of availability problems with Motiv, and collectively full of how awesome they are when they become engaged.
As for the first flash tuner...not by a long shot. Cobb was the first. They also pulled the eject lever quicker than any other vendor. They must have heard that all the Honda boys were buying up N54's and so they bailed before it got bad.
