If your engine runs lean, so it only gets less petrol, and you increase the fuel pressure with this fuel pressure regulator, you will immediately achieve a noticeable increase in performance. If your engine is already running well, you will not feel any improvement with this fuel pressure regulator. If your engine is already running a bit rich and you install this fuel pressure regulator, you can even lose both power and torque.
