A DeatschWerks DW1000c regulator, adjustable from 30 to 120 psi, provided by DeatschWerks. Operating pressure of 80 psi was determined by testing on a dynamometer.
The adjustable range covers the entire range of operable pressures, and the injectors support up to 116 psi, so there is headroom above the operating point.
