mass air

I have a 91 coupe. Put gt-40 upper and lower intake, gt-40 heads, E-303 cam, 70mm T-B, full exhaust, and novi-1000 supercharger. It ran good. Just install 90mm mass air and 30lb. injectors. Now it idles all messed up. It high idles about 1500 rpm, when it kicks down if it does to about 900 it sputters and stalls. Is the computer trying to just use to the change or do I have something else going on. Somebody help please!!!!!!!!!!!!

RE: mass air
