yeah either a boost/vacuum leak somewhere, or the bov you were using isn't closing all the way, and may need adjusting

whoa that would have to be a huge boost leak to do that... did you ever try driving like that? I just installed my intercooler and was curious about what would happen if i ran my bpv to atmosphere as i did not realize how bad of an idea that was until i did it. The car would barely run at idle which it looks like in the begining of your video and as soon as i put it in gear and the car would get a load the car would die. i would check that first. That and i checked the IAC and clean that too. But since this happened as soon as you did your swap i would keep an eye on that valve.
