that whatever he mentioned from Z1 actually hits the market eventually. No doubt that a standalone is the better long-term option. But if you're like me and already have everything else you need for dual intake/MAF except the Selin, simplicity wins. Except that I'm not crazy enough to spend $1K on a used Selin. So for now it's lucky that I am still months away from being ready to actually get my ride running. I can have some patience until then and if something doesn't present itself by then, I'll reevaluate the standalone option.
