I believe the fix is going to be major engine work that will cost thousands. It would seem that you're the latest victim of the #8 cylinder letting go. That sucks man.
You know, the one thing I miss about my previous 3 4.6L stangs is that I never worried about blowing up an engine with an intake/tune.

Pinn posted a link previously that had the specific TSB referenced.

ISSUE:
Some 2011 F-150 and 2011-2012 Mustang vehicles equipped with 5.0L engine may have unauthorized modifications to the powertrain hardware and/or calibration which may result in exceeding component design limits. Such modifications could cause damage to the powertrain and/or void the factory powertrain warranty.

Such modifications could cause damage to the powertrain and/or void the factory powertrain warranty.
The following list contains items that are frequently modified in an effort to increase the engines torque/power output. Modifying these items may, or may not improve the performance, but can lead to drivability issues, DTCs and possibly component failures:
- Air induction system (air box, air filter, zip tube)

If the tune caused the failure then that isn't Ford's fault because it wasn't their work that caused your problem.

Sorry to hear your issues, that sucks!
If your CAI requires a tune and you revert back to stock, you will run lean (throw a CEL) and your car may knock and ping. If you decide to change the car back to stock, I would recommend re-installing the stock airbox.
