[QUOTE="Adandos, post: 10918528, member: 124436"] For high boost applications you want to go returnless... Basically the returnless pump / regulator combo is preset to a single operating pressure and doesn't compensate for boost as does a return style regulator with a boost reference port. Practically speaking this means that the higher the boost you run the smaller your injectors are (due to the drop in differential pressure between the rail and the manifold) Check out or [URL="http://horsepowercalculators.net/e85-calculator/e85-calculator"]E85 upgrades calculator[/URL]... you'll get a complete fuel system calculation factoring in your pressure drop (and oversizing your injectors) or doing a returnless swap... both are doable but I'd do a return if I could.
