Fuel management systems range from piggyback controllers that supplement the factory ECU to standalone engine management units for full fueling and ignition control. Piggyback devices intercept injector signals to add or reduce fuel at high boost; standalone ECUs replace the OEM unit entirely for complete custom mapping. Choose based on your modification level — standalone systems require professional mapping. Shop at GBP Performance — free shipping across Canada.
