I was replacing my starter and to do that I had to remove the intake manifold and the component that sits between the IM and the head, which I believe is called the SP Controller. It has what appears to be the 4 split ports with 4 individual throttles connected to an electrical control box through a single control arm.
Does anyone know what the function of this controller is and is there any way to adjust it or modify it for better performance?
