2012-2013 Boss 302 Mustang

Ford's 2012-2013 Boss 302 Mustang is a very unique high-performance sports car. The 5.0L Coyote engine makes over 400 horsepower from the factory, and JMS was one of the first aftermarket tuners to start modifying this specialty vehicle. We have built and tuned numerous high horsepower 2012 and newer Boss 302's for street, strip and open-track.

 

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 25+ RWHP on un-modified cars 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 Mustangs from the very beginning, since 1993.

 

We are also a master distributor for several premium brand manufacturers and we only sell what we install at our tech center every day, and what we know works best. If you're looking for the right Boss 302 Mustang components and good tech support, JMS is your complete solution. Some of the additional products we sell and install include; cold air induction kits, superchargers and pulleys, stainless steel exhaust systems, fuel system upgrades, engine electronics, and suspension packages.

 

JMS brand electronics were developed especially for high horsepower Mustangs, and they are critically-acclaimed for their superior design and function. Products we manufacture for the 2012-2013 Boss 302 include; PowerMAX FuelMAX fuel pump voltage booster, SparkMAX ignition system voltage booster, Mass Air Modifier, nitrous kits and progressive nitrous controller.
