I was his gauge watcher and With the ksb off it doesn't really move much it was either like 65psi at idle or 160 wot. load on the engine doesn't seem to have any effect on the psi at all, its seems to be strickly rpm related. I got busy later and he punched his what I believe is the regulator and i took one second to go have a look. it was 200psi sitting at like 700rpm and he literally gave the pedal a tiny tap and it jumped instanly to 250psi with ksb still off
