    I just got rid of it.

    The fuel pressure regulator is in the rear of the car for a stock system.
    I agree. It tries to negate the pulses that the injectors cause in the rail. Just for shits and giggles I will keep it on.

    also what that red piece just under the cylinder head exhaust ports?

    Thanks
    I didn't notice anything different...then again I have a loppy cam, so I don't think I can tell the difference between the cam lope and regular vibration.

    They are plug wire boots...they "protect" the wire from the heat from the headers. They came with the car...I have now switched to black ones so they are not so obvious.
