I might have found the problem, jury is still out though. Since I installed this at night, I seemed to have missed a styrofoam peanut in the air filter (I know, think McFly, think!) when I removed the filter, it was plastered up against the honeycomb of the MAS. I cursed a blue streak, removed the offending debris, and replaced the filter (after checking the inside of the filer again, twice) reset the ECU, and let it idle for 20 minutes. The drive home seemed ok, and it didn't die on me whenever I stopped, so maybe that was the problem. I'm going out tonight, so I can give it a good testing on the road. I'll let you know if it acts up anymore. thanks for everyones help on this.

 

Yep, that was the problem. The car runs great now. Thanks again to everyone that helped. Next time, I'll ask BEFORE I install something. You guys rock.
