Pretty much exactly so it will open and dump exhaust once it reaches the springs psi /pressure rating and it is also the least amount of boost you will be able to run unless you get a 4 port I think with a 4 port boost solenoid you can cut the boost level in half to say 5 psi .I don't have one as of yet but am looking into them so I can run less boost in 1st and second and not have to back pedal so often .I run a twin scroll set up with 2 gates both have 7 psi springs in them and I love having twin gates as it doesn't creep at all up top and it spools insanely fast down low .
