This only applies to 2013 Mustang GT's with a manual transmission built on or before 11/30/2012. Cars with the 5.0 from the 2012 model year or older, 2013's with auto trans or other models (Mustang V6, Boss, GT500, etc.) are NOT affected.
Once my car got to about 1000 miles, it seemed like something went wrong with the car. It seem like a plug went bad or a COP was acting funny. The car lost a little torque. It was very subtle, but noticeable enough that I felt it. I also noticed that at near or at WOT, the car sounds and feels like it skips or misfires. I was thinking it was tune related because when the outside temp is in the 30's and 40's it feels really strong, but if it is 70+ like today, the car is just not right.
So tonight I talked to a friend of mine who runs the service department of a local dealership. I asked him if his guys would take a legit look at it or would they tell me something like a hardly noticeable change in feel would be to hard to troubleshoot; and send me on my way. He advised my that this is a known issue for 2013 Mustang GT's with a manual transmission. Ford is working on releasing an update for the computer in two to three weeks along with a TSB. His dealership is piloting the fix with a known user pool. He asked that I sit tight for about a month, as re-flashing the car doesn't fix the problem long-term.
Not every 2013 Mustang GT's with a manual transmission has this problem, but if you are experiencing this problem you're not crazy, imagining things, or having problems with unreliable fuel. It's legit. Give it about a month, then talk to your local dealer.
