3. Once you plug the Mustang tuner into your car, it will automatically power on. Scroll over to "Program Vehicle" and click "Select." Then, select "Custom Tune." You can choose from up to 3 different custom tunes. Select whichever tune you would like to use. Next, select "Skip Options," unless you want to make adjustments to your custom tune (which is not common).

4. Follow the on-screen prompts to download the custom tune to your Mustang. The download process itself may take several minutes.
5. When the Mustang SCT X3/3000 Power Flash Programmer prompts you that it has completed tuning your car, disconnect the tuner from the OBDII port. Next, start your car and make sure it starts and runs smoothly. It is recommended that you let your car sit and idle for 5 minutes after re-flashing your computer so it can relearn the idle before taking it for a drive. After letting it idle for 5 minutes, take the car for a drive and enjoy the extra power!
