2011-2012 Shelby GT500 Computer ECU Custom Tuning

Sort by:

JMS is the original pioneer in modern Mustang computer ECU development and tuning, and in our infancy we solely focused on what was referred to as chip tuning at the time.  We were one of the first companies to develop the programmable chip for mass production, and went on to be instrumental in the creation of what is now the world's largest manufacturer and developer of pre-programmed devices and custom tuning software for Ford vehicles.  When it comes to calibrating the 2011-2012 Shelby GT500 Mustang, our team is the absolute best in the aftermarket and one of the industry's top rated Ford tuning facilities, and used by countless manufacturers for product validation and special calibration engineering.


Our computer calibrations engineer, Monty Johnson is an expert in Ford ECU tuning and works directly with our customers to unleash all of the hidden power trapped in your stock electronics. You will expect to see typical gains of 45+ RWHP on un-modified 2011-2012 Shelby GT500 Mustangs with a basic 93 octane custom tune and SCT handheld programmer. Don't be fooled by other tuners claims! JMS has been in business and custom tuning Ford vehicles from the very beginning, since 1993.
