you dont need a AFPR mike...dont buy into the "dont skimp on fuel hype"...cus when i had my turbo setup..i did the same thing..buying Fuel rails,and FPR's...all you need,is a pump and injectors. When you are pushing past 400 or 500 whp,and your injectors dont cut it anymore..then get a FPR and a fuel rail,until then..just injectors and a pump will do.
