The Sniper EFI Factory refurbish process starts by stripping a used or blemish Sniper EFI throttle body down to the bare casting. From there, our highly trained factory refurbish technicians flow the original fuel injectors. If any injectors fail to meet our flow standards they are replaced with good injectors. All sensors are tested to ensure they accurately report critical engine data to the ECU. Finally, the Sniper ECU and 3.5" Touch Screen handheld are tested and updated with the latest firmware. This process ensures that our factory refurbished Sniper EFI systems are just as reliable as a new unit off the shelf. We include the following new parts; wiring harnesses, coil driver, wideband oxygen sensor, fuel pressure regulator, and any fuel system components that should be included in your kit.
