Default possible map sensor issue?

Ok so i have a 86 5.0 i just got done putting ported e7 heads on, a cobra upper and lower intake, and an x-303 cam in it. When the map vacuum line is on the idle shoots way up to about 2500 but doesnt miss or anything. When i take the vacuum line off it idles back down but starts running rich and misses bad. Is there anyway to fix the sensor for the cam? Is there anything i can do? The tps sensor is also on .9, tomorrow i need to make the holes bigger so i can adjust it more closer to .97. The lobe separation angle on the cam also is 112. Thanks for any info.
