Prepare yourself for the next generation of handheld tuners! Introducing the X3 Power Flash Tuner from SCT. The X3 is the latest development in the legendary Xcalibrator Line of flash tuning tools to come out of SCT's ingenious minds.

Based off of SCT's premier LiveWire Tuner, the X3 takes the Xcalibrator to a whole new level with features such as enhanced data logging with 8 times the onboard memory (128MB Total!), an upgraded 4-line backlit display, and the ability to hold not only custom tunes, but also dyno proven strategy tunes for your stock or mostly stock cars at the same time!

The Xcalibrator 3 features stand alone tune adjustments for tweaking both your custom tunes and the strategy tunes without the need for a computer or laptop. This is perfect for not only the knowledgeable owner to tweak their tune to track conditions, but also for the basic user to compensate for items such as gear and tire size changes.

If you want more power, more control, and better gas mileage at the same time, the SCT X3 Power Flash Tuner is the answer to your prayers!



Works on all V6, GT, Bullitt, Mach 1, and Cobras from 96-11.
Gains on stock GT's around 17 RWHP and 20 ft-lbs of torque. More on V6 and S/C Cobra.
The 2011 Mustang 5.0L tune files add up to 28 Rear Wheel Horsepower & 34ft-lbs of Torque to the automatic transmission equipped Mustang, and a tire shredding 32 Rear Wheel Horsepower & 31ft-lbs of Torque to the 6 speed manual transmission vehicles.
