Mustang Performance Packages

Ford’s performance accessory division, Ford Performance, is taking a good thing and making it better. New performance packages boost the power and torque of the 2015-17 Ford Mustang with the EcoBoost turbocharged four-cylinder and the GT with 5.0-liter V-8 engine. Each package is backed by a Ford Performance warranty when fitted by an authorized installer, plus the performance computer reprogramming is 50-state emissions-compliant.

The Mustang EcoBoost gets perhaps the most notable increase for the money with its EcoBoost Performance Calibration Kit. For $699, the package includes a cold air intake with conical air filter and handheld programmer to increase horsepower from 310 horsepower to 335 hp, and torque from 320 pounds-feet to 390 pounds-feet. Ford notes bigger gains below its peak number of up to 100 hp at 6,000 rpm.

On the V-8 side, three available packages range from a performance calibration and drop-in air filter to borrowed components from the track-ready Shelby GT350 for increasing power. Beyond bigger numbers, manual-transmission GT Mustangs are calibrated to include a no-lift shift feature that allows drivers to keep the accelerator floored during shifting to maximize acceleration. The automatic transmission also receives updated performance calibration.

The GT’s Performance Calibration Power Pack 1 ($599) includes the performance-tuned calibration and a drop-in K&N performance air filter for gains of 13 hp and 16 pounds-feet of torque with 40 more pounds-feet at 1,500 rpm. The GT Cold Air Intake & Calibration Power Pack 2 is $949 and replaces the drop-in filter with a conical cold-air intake from the GT350, plus a larger 87-mm throttle body. With the included calibration, power is up 21 hp and 24 pounds-feet of torque.

The most-extreme GT package is Performance Intake & Calibration Power Pack 3. For $2,395, the third package adds a GT350 intake manifold to the second power package’s contents and boosts peak power 37 hp and 5 pounds-feet of torque to 472 hp and 405 pounds-feet of torque. Ford Performance says a mighty 60 hp is gained at the now-7,500-rpm redline, up from 7,000 rpm.
