Ford Releases TSB Warning to Prevent Tuning For Mustang

Usually when Ford issues a Technical Service Bulletin is mainly to correct an existing problem or defect with a car. Until now, Ford has issued three TSBs for the Mustangs manufactured after 2011 to correct problems with the clutch, fuel pump and cold shifting. However Ford has released the latest TSB for a different problem.

Ford said it "addresses the fact that“ some 2011 F-150 and 2011-2012 Mustangs equipped with the 5.0L engine may have unauthorized modifications to the power train hardware, which may result in exceeding component limits.Such modifications could cause damage to the powertrain and/or void the factory powertrain warranty. Attempting to increase the engine output via recalibrating the PCM may result in poor drivability or component failures.

A Ford representative said “customization is a big part of the Mustang ownership experience. This [TSB] is designed to alert people to the possible damage and warranty ‘voiding’ one can incur if they modify their vehicles beyond factory specifications.”

How will this affect this the owners of 2011+Mustangs? First of all, Ford can not automatically void your warranty due to the aftermarket modifications. The fact has backup in the Magnuson-Moss Warranty Act of 1975 which states that it must be proven that an aftermarket part directly caused a failure to original equipment parts to void a warranty.

Increasing horsepower and torque can be done safely, although it can be done in a harmful way that will damage the engine internal components. Aftermarket products designed and produced correctly will increase your Mustang’s performance and will not void your warranty, a fact stated by MustangDaily.com.
