My rig has an aftermarket high flow fuel pump with an adjustable regulator and gauge. The gauge goes to 60 but it looks like mine has been set to 62. Does that sound right? What would be the effect if I raised or lowered it?

 

62 is with in factory specs. raising it or lowering it to Much will effect the tune and the car would have to be returned to compensate for added fuel pressure or lowered fuel pressure.

 

Thanks man! Is 62 common for all or most injected engines?

 

it is used for your injector tables, 60 is the common range and what the preset tables are set to for all of our main injectors (42s, 60s, 80s)

 

i would say 43.5 is most common but i know Alot of newer gm cars run 58-62 psi.
