Review on 303000 Engine Control System Xfisportsman by Adam Johnson

Well built kit but not complete. You still need to buy the necessary spare parts. NO PACKING LIST! Incomplete instructions. I don't know if the kit was complete. The wiring harnesses do not specify which row or cylinder to route the injector connectors to. If you're not using a FAST 4 throttle body/injector, you're on your own. Online chat with FAST tech support provides incorrect information. That's a lot of money for such a poorly thought out product. I do not recommend it to anyone who has not already put this system on the engine and solved the mystery.
