I just picked up a non-turbo 2.0 FPR from the junkyard and tossed it on. 48 psi base pressure is above what even a rewired 255hp will overrun to; adjust injector compensation for the extra fuel, voila- no more rich idle, 2 mpg increase in my gas mileage, and a good bit more fuel out of my injectors. Much cheaper and easier than all the aftermarket junk as long as you're not running more than 25 psi, which is when the fuel pressure gets too high and you then need the afpr to prevent overrun at a lower base pressure.
