    I just purchased a R33 GTST and I want to get an after market blow off valve for it. From what i've researched the install seems pretty straight forward.

    So I installed a greddy manifold and fuel rail on my RB25DET Neo and I’m having trouble setting the correct fuel pressure (43psi without vacuum). Every time I try set it the needle on the gauge flutters like mad. I can set the fuel pressure just below 40psi and the needle stays still. As soon as...
