Sequential Multiport EFI

thanks I just saw a kit from an outfit called Affordable for about a 1,000 less the eddy's kit , the reason I am thinking multiport is exactly what you just said , Idle and low speed , wide open the Holly 950hp is great but no choke circuit makes idle and low speed a bit of an issue especially now that the temps are dropping , that and if top end ping is what caused my head gasket failure this summer then EFI should offer some protection from that .I am not hung up on the sequential part but I am thinking I want a system that has more control than a basic TBI setup which is why I am looking at multiport .
