SCT Handheld Programmer with Lund Racing Custom Tune

For an outline of the tune order process, CLICK HERE!

2015-2017 Mustang V6 custom tuning is currently not available from Lund Racing. This device also does not include preloaded tunes from SCT for the 2016 Mustang V6 at this time.

NOTE: When selecting the "Add Lethal Performance Custom Tune" option from the drop down, you will be emailed a form to fill out with your vehicles modifications after the order is processed.

 *Note: For 2011-2014 Mustang 5.0L Coyote customers... Cammed tunes are available for manual AND automatic transmissions now (Custom Tune option MUST be selected). The cammed tune is for "OFF ROAD" USE ONLY! This is a novelty tune, so some minor driveability issues are to be expected just as you would have with a car running a large camshaft, so those quirks will not be chased by Lund Racing.

 *Note: Flex Fuel capability is only compatible with 2011+ Coyote 5.0L and Voodoo 5.2L (GT350 and GT350R). 2011-2014 Mustang 5.0L require minimum 47 lb fuel injectors for all E85 / Flex Fuel bolt on tunes.

Now standard at Lethal Performance! When selecting the "Add Lethal Performance Custom Tune" option, you will receive 2 custom tunes STANDARD! Each additional tune is $100.

From the factory, your vehicle's computer is calibrated for the masses, designed with the average driver in mind, not the performance enthusiast. This not only leaves valuable Horsepower & Torque hidden inside your vehicle, but it also makes for a mediocre driving experience. The SCT X4 Power Flash unlocks your vehicle’s hidden performance by optimizing your vehicle’s computer for Maximum Horsepower, Torque, Increased Throttle Response, Firmer Shifts & even Increased Fuel Mileage!

Massive Full-Color Screen in a More Compact Package

The X4 is SCT Performance's giant leap into the future of vehicle PCM tuning and custom tuning. The SCT X4 replaced the venerable, but aging SCT X-Cal 3 and SF3 handheld tuners and offers up a massive improvement in both ergonomics, speed, versatility, and tuning capability all in one awesome device. The SCT X4 tuner has a massive 2.6" x 5.5" full-color LCD screen that makes the X4's tuning, vehicle info, datalogging, and other menus extremely easy to read and navigate. Despite the larger and more advanced screen, the X4 is actually more compact than the outgoing SCT SF3 and X-Cal 3, making it easier to store and handle during tuning or maintenance. The X4 also does away with the massive OBD-II cable that the SF3 and X-Cal 3 needed to lunk around, and replaces it with a smaller and more unassuming cable with an new port on the device itself that allows you to unplug the cable completely.

Features Built-In WiFi and the Ability to Hold 10 Custom Tunes

The larger screen is paired with a revised control interface with new buttons that are more responsive, easier to use, and less clunky than SCT's older tuners. By far the most impressive feature of the X4 is it's built-in WiFi functionality that allows it to connect wirelessly with your home PC to download new tunes, firmware, and other software without the hassles of using a USB cord. The X4 can hold up to 10 custom tunes on top of its standard canned performance tunes to give you the ability to have tuning for any applications that you find yourself or your vehicle. The X4 even has two analog ports that allow you to hook up expandable probes and sensors to read data and PIDs that aren't output through your vehicle's OBD-II port. The X4 can display a wide variety of different gauges and other performance information and even automatically rotates with the device's orientation which makes it a more than adequate vehicle monitor, especially when combined with SCT's additional suction cup mount or other vehicle map. The X4 is the last tuning device that your vehicle will ever need and will take custom tuning to a whole other level.

This tuner is pre-loaded with SCT performance tunes for most 1996 and newer Ford Cars & Trucks
