Fuel Systems When modifying your vehicle the most important thing is to make sure you've got enough fuel to handle the power you'd like to make. The first step would be to figure out what power level you're looking to support. From that you can choose the appropriate system. We offer fuel system upgrades starting from a simple line upgrade all the way up to 2000rwhp complete systems. Making sure to pick the correct injector size is also very important. You want to choose the injector that best fits the HP level you're looking to support and the fuel type you're looking to run. Going with too large of an injector may be harder for your tuner to tune and may also sacrifice adjustability. We offer a wide variety of high quality fuel injectors for all applications from names like Injector Dynamics, Deatschwerks, Fuel Injector Clinic, Ford Performance and more!
