2015-2017 Mustang GT Performance Calibration/Cold Air Intake/Throttle Body Power Package Stage 2


  • Coverage: Fits 2015-2017 Mustang GT. Note that these power packs are for North American Mustang spec only at this time
  • Universal: All calibrations available for manual and automatic transmission vehicles
  • Piece of Mind: The only cold air intake and throttle body upgrade backed by a comprehensive 3 year 36,000 mile Ford Performance drivetrain warranty. You wont find this kind of performance and warranty protection anywhere else.
  • Exclusive Features: No-lift shift strategy and enhanced throttle response not available from anyone else.
  • Proprietary Engineering: All Ford Performance calibrations feature exclusive Ford proprietary software and engineering not available from anyone else. These are not simple settings changes that other tuners or mail order companies provide using the incomplete and limited tuning software available to them. Ford engineers have complete control and develop unique software from the ground up to deliver unmatched performance and reliability.
  • Tested and Proven: The ONLY durability tested tunes available. Don't risk your warranty and powertrain durability with anything else.
  • Validated: The ONLY tunes validated for extreme conditions such high altitude, extreme heat, and extreme cold.
  • Investment: You have to ask yourself, Why did it take Ford two years to develop, test, and emissions certify these tunes when the rest of the mail order shops and tuners had theirs done? Because Ford invested the time and resources necessary to do them right.
  • Emission Legal: All Ford Performance calibrations are 50 state legal with CARB EO D-598-19.
  • Flexibility: Allows for gear ratio changes up to 4.09:1. Optimizes the vehicle performance and corrects the speedometer for gear ratio swaps. The end user has the ability to easily change this setting at any time.
  • Optimized Shifting: Automatic calibrations feature optimized performance shift schedule
  • Premium: Premium fuel, 91 octane or higher, is required. The tuning is optimized for both 91 and 93 octane fuel including the oxygenated fuels used in California.
  • Breathe Easy: The Stage 2 Power Pack includes the following induction enhancements:
    • Shelby GT350 Open element Cold Air Box with larger diameter inlet tube. The only warranty safe and emission legal open element cold air box available.
    • Shelby GT350 87mm Throttle Body (versus 80mm stock throttle body) with Ford Performance exclusive manifold adapter. A Plug and play upgrade that compliments the huge cold air box.
  • More Power: 21HP and 24TQ peak gains over stock. Unlike other tune providers Ford only advertises the peak gains (not just a random maximum gain figure). The peak gain is a real apples to apples comparison of what indicates a performance improvement. So, your stock Mustang GT is advertised to make a peak 435HP at the flywheel. This tune will bring that number to over 456HP at the flywheel. Don't be misled by other tuners claims of "max" power gains. The "max" gain is not an apples to apples comparison, it is just the largest gain they claim from somewhere else on the rpm band.
  • Power You Can Actually Use: 40TQ gain at 1,500RPM. That's right, a huge torque gain down low where you want it most. Better start saving money for new rear tires.
  • Easy Installation: Includes USB dongle that connects your laptop computer to your vehicle OBDII diagnostic port. Laptop computer (not included) with internet access required for installation.
  • Note: At this time Power Packs are sold separately and cannot be upgraded without the purchase of an entire kit. For example, you cannot install a Stage 2 kit and then later upgrade to a Stage 3 without purchasing the entire Stage 3 kit. You won't be able to buy the individual parts and new tune from Ford Performance to convert a Stage 2 kit to a Stage 3.
  • Kit contains:
    • 1-Vacuum T, 3/8
    • 1-Throttle body adapter w/ 4 screws
    • 1-Wire tie w/25mm offset
    • 1-Air cleaner assembly

Reviewer: Anthony Gardere from Apple Valley, CA United States  
Kudos to for amazing shipping time! Ordered and received it the next day! The added power and quick and easy installation made for a great purchase! I would urge all stang owners to get this! This went on my 2017 GT with 3.73 axle and Magnaflow straight through exhaust.
