SCT X4 Tuner Review

The SCT X4 tuner has the ability to significantly increase the power and torque of your vehicle. The device is preloaded with Dyno tuning files that have been tested and have been professionally created.

It can also connect to Wi-Fi, just like most contemporary devices, making it simple to get software updates. There are several disadvantages of the device, such as its small size and insufficient battery life.

Both installation and programming of the SCT X4 take a matter of minutes. The backlit display of this tuner makes it very easy to view real-time data, as well as sensor data, from the device in question.

Some tuning settings have already been programmed into the SCT X4 in order to improve the overall performance of your vehicle. However, if you do not wish to use them, you can load up to ten custom tuning files instead.
