I believe a new sensor is supposed to cut off the pumps at between 1.2-1.4 bar. The older they get, the more sensitive they seem to get and the threshold drops.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
