Fueling is controlled from a re-flashed ECU and standalone G3 controller box that controls the secondary fuel injectors. As of now we are the only aftermarket company running 4 injectors but both Polaris and Ski-doo run them on their turbo sleds direct from the factory. This provides better throttle res
