Would there be any advantage to switching to design 2 fuel injectors when I do my intake swap next week? Aledgedly they feature 4 fuel outlets, offer better combustion chamber fuel atomazation, better performance while maintaing fuel economy. Or would i do just as good cleaning the old originals up. 91,000, miles stock GT engine. I'm on a tight budget and cannot afford everything I see. Love this forum, Thanks Bob for the invite.
