2G Sputtering and popping

[TuJay]

yeah you’re probably tired of seeing me post but I’m still new to this stuff. So recently my car started acting weird. I know it runs super rich and I put a new upstream o2 in it and it helped a bit but below 2500 rpm I’ll have very little acceleration and it’ll backfire and pop until I get into boost at 2.5k and it’ll run fine? What the hell is going on?

I figured it out, Need to recirculate my BOV or get a MAFT. Just bought this car and didn't know much until I spent the better part of today on this website .
