i was planning on getting a bci but dont kno what one to get. I was always taught if your going to do something do it right, so I wanted to get the stage 5 intake but it says. (EFI LIVE NEEDED FOR MAF TUNING). from my understanding from the website http://www.billscustomintakes.com/ the stage 5 5" intake needs efi to work. correct me if am wrong?. I dont have efi currently but am planning on getting it soon. anyone with suggestions on what to get or have a 5" bci and could help me out from experience would help.
