Boostvalve manual boost controllers allow simple adjustment and reliable performance.  Dial in your peak boost with the adjuster knob and then lock in place.  Once set, your peak boost will hold steady at your preset level, no more need to re-adjust later, just set  and forget, its that reliable, once set you can rely on the boostvalve to hold pressure giving you the fasted spool time and least possible boost spikes.
