2007-2009 Shelby GT500 Performance Power Packages

JMS was one of the first aftermarket tuners to start modifying the 2007 Shelby GT500 Mustang with the SVT 5.4L supercharged engine. We have built and tuned numerous high horsepower Shelby's ranging from 750 to over 1,000 RWHP, and we have used that knowledge to develop reliable horsepower packages using the same parts we install in our well documented and publicized mega-power GT500's.
