When tuning the turbo for the S660, if you are doing tuning that requires a large capacity fuel pump or injectors, such as replacing the turbine, changing the boost pressure, or changing the specifications in the ECU, the original fuel pressure regulator's setting of 3.1 to 3.6 kgf/cm2 will not be able to handle the appropriate amount of fuel or the situation that matches the tuning.
By simply replacing it with the reinforced pressure regulator set, you can ensure optimal and stable fuel pressure set at 4.0Kgf/㎠, making it an essential part for turbo tuning of the S660.
