This product is specifically designed to address the wide fuel pressure swing inherent to the F-LS1 fuel system where the pressure regulator is located on the fuel pump module at the back of the car. This system will provide rock solid pressure regulation (assuming adequate pump volume) for high power applications. Stable fuel pressure allows for safe and consistent motor tuning and support of much higher power levels. Use of the pressure port  for manifold referenced fuel pressure will extend the HP support of existing injectors and allow for the use of extremely large injectors while still being able to maintain decent idle and driveability characteristics.
