My car has 60lb injectors, 255lph fuel pump and a kirban adjustable fuel pressure regulator. At idle fuel pressure is at around 32 psi. I took it out for a 3rd gear pull up to redline on the highway and pressure climbs without falling off up to around 51 psi.
Anybody have any thoughts or concerns regarding my fuel pressure? Maybe someone has insight on what their car is set at? I was thinking stock spec pressure at idle is typically 35-45psi but peaking at 51psi seems alright. Doesn't seem to be hurting anything, but I havent checked my plugs for 1,000 miles and sometimes coming down to idle and starting it first thing in the morning causes the car to stumble pretty bad. Car holds fuel pressure after shut-off for a long time, so no leaks.

P.S. car is tuned at this fuel pressure
