It sounds like your firmware being updated and a revised file did the trick! Definitely still put some miles on it and let us know how it goes. If you have any questions or need some assistance, we'll gladly get you squared away!

im pretty sure the car is supposed to do that. My car did it off the dealer lot and it goes away after letting the car warm up for a min or two. I heard it has something to do with the Tri vci

The stock cars do not have the issue that I was speaking of. It only happened once I added CAI and tune. I've been selling Ford's for over two years now, so I know how the new ones drive even with a cold start. This was a more "violent" shake than what you would normally expect from a cold V8. Since the re-tune, it hasn't done it, and the idle has been much smoother. The next real test would be at the autocross next weekend to see if anything else comes up.
