I know this has been brought up plenty of times but there is one thing that i am still unclear about...with the greddy turbo timer do i need to hook up the brown and pruple wire? i'm not sure what wire i'm suppose to hook up the purple wire to...i know it's the speed signal one but where which wire is it...also with my boost controller as soon as i turn the damn thing on i'm showing 7-8 psi...that's with both boost settings at min...please help....
