<div class='quotetop'>QUOTE(AK1)</div><div class='quotemain'>If your FPR is not referencing boost and increasing pressure say on a 1:1 ratio under boost conditions then you're just going to be running lean with all that air and not matching fuel quantity. Â*
</div>FWIW, the stock fuel pressure regulator on the 4G64 Spyder engine is a 1:1 rising rate unit. I did not have to change it for my turbo install. It works great. Base pressure is also higher than a turbo model car. It's 48 instead of 42. I get 60psi fuel pressure at 10psi boost. It would fit a galant fuel rail, if you wanted to get one. They are under $50 brand new from the dealership (part number MD322829).
