Angry cobalt won't run under boost

so, I'm driving my car and i go to pull out of an intersection and suddenly i fell a huge dramatic drop in power, and the car barley ran, i smelled gas, I had to limp the car home, I've tried taking the battery terminal off to reset the computer. The car misfires it seems when boosted, but idles fine, Im really lost, the car has a zzp intercooler, zzp 2.9 pulley and bigger injectors, but in all i need some serious advice how to fix this problem, i sure as hell don't wanna ride the bus to school!!

the car will idle fine, but soon as you give it some fuel it will post a small amount and then when you boost a lot it will completely bog off and sputter and sometimes die...

The clogged cat make sense. I don't see it being coil pack... Take your down pipe off and take it down the street
