Take your 2019 Bullitt Mustang to the next level with SCT's X4 tuning device. This is the latest evolution of the X series of tuning devices from SCT. SCT's X4 features great improvements in design and use. This unit is a smaller, more compact device than the X3 it replaces.

The X4 features a larger, brighter, easy to read color screen with auto dim and user adjustable portrait and landscape modes. The device holds up to 10 custom tunes which can be supplied by SCT custom tuning dealers and also includes pre-loaded strategy files from SCT.

Now with built in Wifi, the device can be connected to any wireless network and will allow you to install any software updates released by SCT right through the device without a PC.

In addition, the X4 offers improved datalogging capabilities right through the device or when used in conjunction with a laptop and SCT's Live Link software.

Tuner & tune
The SCT X4 tuner is simple to update and use. It prompts to backup the stock settings before uploading the Steeda tune so you don't lose the Ford factory configuration. The tune is specific to the engine and strategy code (something others don't necessarily do), so it's optimized for your powertrain. The tune itself is excellent. I noticed smoother throttle tip-in, a faster rise in the power curve, and more torque in both partial and WOT positions. The tune really brings out the best in a naturally aspirated Coyote. It's an easy and cost effective way to add some more "Wow!" to your Bullitt!
