Ford Mustang owners don't have much choice in the matter anyway because most tuners prefer tuning with SCT. Overall I give it 4 out of 5 stars and would recommend. SCT tech support was prompt and helpful during the two occasions I needed their help which can go a long way when dealing with finicky devices like this one. SCT X4 comes with a pre-loaded tune file that is proven to increase horsepower and torque. You can gain up to 150 horsepower on your stock diesel truck or up to 74 ponies on your gas-fueled chariot.

The more compact size of the device makes it feel more portable and the general fit and finish is better than the older models.ĭatalogging with a laptop/Livelink software can be a bit challenging as it seems to be inconsistent on whether it can log starting with the key on/engine off, or log regardless of engine status as long as the key is on. The X4 tuner will reprogram your ride to give it the ultimate boost in power, torque, and throttle response. The screen layout can be customized to see more (or less) on the screen while datalogging with the handheld. The handheld is an improvement over the outgoing X3 as the LCD screen makes it easier to read at night.
