2g mas idling

after installing my 2g mas(both side honeycombs removed), my car has trouble trying to stay alive on stops and has a hard time trying to stay idle below 2500 revs even with a little step on the gas. no leaks, no vacuum leaks. everything is solid except for the tuning part. I've got the S-AFC and richened it up a bit. shitty part...i have no wideband and no logger to see if it is knocking. I just installed the 2g mas just to see how its like and understand more about tuning. Yeah, i know it's kind of stupid, but i did this for a short time and it's fun experimenting of my car. Just wondering if the 2g mas is supposed to idle like this?

-big 16g
-bored .020 over
-mildly ported 1g head, stock cams
-ported 2g manifold
-ported o2
-3" exhaust system
-190 fuel pump

-VAFC (tuned for 1g mas...drives PERFECT w/1g mas)
