5 Star Custom Tunes w/ SCT BDX Device (1999 - 2004 Mustang 3.8L)

Why Tune My Vehicle?

From the factory, your Mustang’s PCM is calibrated for the average driver, leaving hidden horsepower & torque untapped. This often results in sluggish throttle response and a less engaging driving experience. With a 5 Star Custom Tune, your vehicle is recalibrated for maximum power, torque, throttle response, cleaner shift points, and improved efficiency—delivering a more exciting and enjoyable ride.

Why 5 Star Tuning?

5 Star Tuning is the industry leader in Ford and GM tuning for trucks, cars, SUVs, and motorhomes. Unlike “one-size-fits-all” solutions, our calibrations are custom-tailored to your specific goals, whether that’s adding power, maximizing torque, or enhancing overall drivability. Best of all, we design every tune with reliability and safety in mind.

Dyno & Street Proven Tunes

Every tune has been dyno developed, refined, street tested, and tow tested using our own vehicles. With over 1 million miles of real-world testing, you can trust 5 Star for proven results and top quality.

Free Tunes for Life

As a Tunes for Life member, any future modifications you make to your Mustang are covered with free tune updates for as long as you own the car. This ensures your vehicle continues to run at peak performance with every upgrade. For more details, call 1-855-827-7223.

Performance Benefits

  • Unlocks hidden horsepower & torque
  • Sharper throttle response
  • Optimized shift points for smoother driving
  • Improved fuel efficiency
  • Removes the factory speed limiter
  • Enhances daily driving and performance

How Do We Get More Performance?

Our calibration team adjusts fuel tables, drive-by-wire response, ignition timing, torque converter strategies, shift pressures, and transmission mapping to maximize performance from your 3.8L Mustang.

What Can My SCT BDX Device Do?

  • Store up to 10 custom tunes
  • Monitor live engine parameters (RPM, speed, coolant temps, and more)
  • Record datalogs for future modifications and fine-tuning
  • Retain a copy of your factory tune for easy return to stock
  • Supports Wi-Fi for wireless updates

How Does the Process Work?

  1. Place your order online or by phone and provide your vehicle information.
  2. If your ECU calibration is up to date, tunes will be built based on your submitted info. If not, a blank device will be shipped.
  3. Connect the BDX to your vehicle’s OBD-II port, select Vehicle Info, and record your ECU strategy code.
  4. Email the code(s) to 5 Star Tuning.
  5. You’ll receive your custom tunes via email—download them and load onto your BDX device.
  6. Plug the device back into your Mustang, select Program Vehicle, choose your custom tune, and follow the prompts.

Installation & Support

The installation process is simple and tool-free, typically taking only 5–10 minutes. For assistance, call 1-855-827-7223 or email sales@beefcakeracing.com.
