yeh.. sounds like you have a boost leak coming out of the BOV...
if your running stock electronics the AFM already measured the air and is spraying tons of fuel...
with a boost/air leak AFTER the AFM along the intercooler piping or BOV is bad, since the AFM doesnt detect it so your running really really rich.. hence the bogging and mis-firing.. have you noticed poor poor MPG?!
This is why it bogs and you cant build boost properly
