Inliners International Forums General Discussion Blown and Injected Siamese Sequential Port Fuel Injection

Thanks. Guess I need to find an adjustable rising rate fuel pressure regulator. A normal 1 to 1 ratio would be 33 psi off boost and 43 psi at 10 psi boost. Or would a 1.5 or 2 to 1 rise be better, but havent seen those available?
