Hmmm??? I can see Ford not wanting to warranty damage done by a hack tuner. I agree 100%! BUT, Ford sales a Performance Tuner and K&N Filter combo for the 2011-2014 Mustang GT and eligible for warranty when installed by dealer. Ford also sales a 525HP and 624HP Supercharger for the GT, so I call nonsense on the TSB. If that were true, Ford would not sell them, and Ford would not offer a 12 month - 12,000 mile warranty when installed by a Ford dealer.
Paul, I would like to see pics of your TREMOR when it arrives.

james the tsb is not nonsense...it simply states that if a 5.0 shows up with any aftermarket pcm flash, or power adder mods, PLUS piston damage, they will not warranty it......the ford motorsport power adders come with a flash device or another pcm with the proper tunes in them...from ford.
some engines are more forgiving to detonation and "on the edge" a/f ratios than others and it doesn't seem the 5.0 is one of them
heres the tsb:
FORD: 2011-2012 Mustang
2011 F-150
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.
ACTION:
Follow the Service Guidelines.
SERVICE GUIDELINES
Inform owners that the current 5.0L calibrations adjust fuel and spark settings for maximum performance with production hardware, while protecting the engine over a wide range of operating conditions. This includes a knock sensor calibration enabling optimized performance based on fuel grade usage see Owner's Guide for details. Aftermarket hardware and calibrations risk damage to the engine.
Unauthorized calibration modifications may or may not be detectable using standard tools Integrated Diagnostic System (IDS), Portable Diagnostic Software (PDS), NGS+ VCM. Changes can be made to the calibration and flashed to the powertrain control module (PCM) through the on-board diagnostics (OBD) port. Physical modifications to the hardware may or may not be present. If aftermarket power/torque-increasing modifications are suspected, care should be taken to record and store the following items: Permanent diagnostic trouble codes (DTCs), pending DTCs, freeze frame data, mode 6 and mode 9 data. The data should be printed and attached to the repair order for later reference.
The DTCs, freeze frame data, mode 6 and 9 data can be obtained by using the IDS, PDS or NGS+VCM under tool box selection. The powertrain tab will provide the OBD test modes tab and mode 6 and 9 data selection after the vehicle has been identified.
Attempting to increase the engine output via recalibrating the PCM may result in poor drivability, DTCs, or component failures. A partial list of calibration induced component failures is given below:
Excessive Cylinder Pressure And Temperature
Piston damage
Spark over-advanced (knock-induced damage)
Insufficient enrichment
Catalyst damage
Increased RPM Limit/Overspeed
Piston damage
Connecting rod damage
Oil pump damage
Catalyst damage
Clutch damage
Knock Sensor Calibration Changes
Piston and/or ring damage due to improper knock control
Hardware Modifications:
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)
Super chargers
Nitrous oxide systems
Throttle bodies
Exhaust air path/system
Review Engine Damage:
Common failures associated with unauthorized modifications have included:
DTCs present indicating cylinder misfires (P0300 - P0308)
Cylinder/piston damage resulting in a misfire, low compression, noise
Unusual Clutch wear/damage
Piston damage - light knock (Figure 1)
Piston damage - heavy knock (Figure 2)
