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.
