    Anyone know what this goes to? Was on the back side of supercharger leading into TB. I capped it off for now and is running fine. Maybe boost Guage port?

    Vacuum from your IAC to that idle diaphragm under the throttle body cable linkage area (if you have one). If you don't have one it shouldn't affect anything as you have it capped. If you do, it may cause higher idle at start as you have created a vacuum leak essentially which causes the diaphragm to open and push the throttle to higher rpms
