I have had nothing but good experience with corksport stuff..but fuel pump internals with this platform are a massive link when going mods, the corksport ones seem overkill until there are bigger flowing injectors available (and thats if you are going around 500hp plus with out 5th port). Seeing Voltron, Freek and rfinkle are now partnered up with corksport..maybe bigger injectors r in the works.
