Remember the awesome TracKey engine calibration that Ford offered on the 2012-’13 Boss 302? Well, now it’s available to the general public for the 2014.5 manual-transmission-equipped Mustang GT. It features the same special key as the Boss design and enables special performance calibrations to the engine management system. It must be dealer installed and can be purchased under part number M-14204-MGTTKA for the 2014.5 Mustang GT. It’s still available for BOSS owners as well, using part number M-14204-MBTKA.

The TracKey changes more than 200 engine management parameters, increases low-end torque, and adds the two-stage launch control feature like what’s used in the Cobra Jet race car. Even the idle is more aggressive – the variable camshaft timing, spark maps, engine braking, fuel control and other parameters are all tweaked to give the driver a better experience behind the wheel. The best part? Simply switch back to the standard key, and the car’s back in daily-driver mode.

Also now available is the Track Cal option for 2013-’14 Mustang owners. sold under part number M-14204-MGTTC. The Track Cal offers the same type of performance enhancements, but is installed using Ford Racing’s familiar Pro Cal flash tool – it does not come with a separate ignition key. The Track Cal alters the same types of engine parameters as the TracKey – but the lopey idle characteristics can be turned off. 

Gains of up to 60 pound-feet of torque at 1500 RPM and 16 horsepower and 7 pound-feet are available at the peak using the required 93 octane pump fuel. 

Both the TracKey and Track Cal are 50-state legal for the 2013-14 Mustang GT with manual transmission. The 2014.5 (after 7/1/13 build date) GT’s can use the TracKey only. Track Cal has an MSRP of $559 while the TracKey carries a $425 pricetag, plus whatever your dealer charges to install it. Solid pricing when you consider the fact that these calibrations have been optimized by Ford’s own engineers.
