s30kid Posted April 8, 2015 Share Posted April 8, 2015 I just had a quick question. I just installed a walbro 255 from summit racing that is rated up to 60psi along with a pallnet 11mm o-ring fuel rail and a fuelab boost reference pressure regulator. I have the idle pressure set to 40psi. At 15psi of boost I should be seeing 55psi of fuel correct? Anyway I'm seeing 60 psi on my gauge under boost and at cruising speed the needle is going crazy around 45psi. But under boost the neelde is stable. Is this okay or should I be concerned?
