Your 2005 to 2009 Mustang GT's factory fuel system can actually support quite a bit of horsepower before you need to jump up to larger injectors, much less a dual fuel pump or complete fuel system. Still, if you're putting together a vicious supercharger or turbocharger tuner kit or even a naturally-aspirated Pony with every bolt-on performance part in our inventory, then you'll be needing fuel upgrades in a heck of a hurry. Fuel system upgrades are really only required for serious modifications like supercharger or nitrous kit. If you're already running a forced induction system, add even more power with our exhaust upgrades .
