Show original supplier description

The Lund Racing Rev-X Tuner by SCT is engineered to unlock the full potential of your 2011-2014 Ford Mustang GT or 2012-2013 Ford Mustang BOSS 302. This quality module delivers significant improvements in horsepower, torque, and overall performance, providing a guaranteed maximum, safe, and reliable power increase. The system includes the SCT Rev-X tuning device and one custom tune file specifically developed by Lund Racing. Installation is straightforward, with an approximate time of 20 minutes, making it a simple upgrade for most enthusiasts. The package contains the Rev-X device, the custom Lund Racing tune file, an HDMI/OBDII interface cable, and a Micro USB cable. This tuner requires the use of 91-93 octane fuel. It is important to note that this product will not ship to California, and Lund Racing will not provide custom tune files for residents of that state. The tuner is exclusively designed for the 2011-2014 Ford Mustang GT and the 2012-2013 Ford Mustang BOSS 302 models. Lund Racing also offers a Safety and Performance Review service for mail-order tunes on 2011 and newer models, which can help diagnose any potential mechanical or installation-related issues.
