[QUOTE="turbology, post: 508048, member: 10223"] Most, if not all, cars use fuel presure regulator. And depend on your Intake Manifold Pressure, your fuel pressure in fuel rail increase and decrease depend on your throttle. Example, at idle is 10psi(manifold in vacuum), and 20psi when WOT (no vacuum) By increasing the fuel pressure, you can get more fuel into engine without increase the injectors size. Here is the interesting part : alot of "self-acclaim" mechanics don't care or don't know how to adjust "fuel map". So increase your fuel pressure with adjustable FPR(Fuel Pressure Regulator) is the EASIEST WAY to increase your fuel when you Forced Induction it. Because adjustable FPR increase your fuel pressure LINEAR-ly, you will have WAY TOO RICH mixture before the turbo spool in. Result, you get 1. white smoke, 2. fault spark plug, 3. clog CAT, 4. clog O2 sensors, 5. short lifespan Turbo, and etc bad things. Will it work with my new TURBO + adjustable FPR? Yes. But how long?
