Do you have a log file with AFRs showing when the problem happens?

i do not. i can tell you that i shift at 6400 rpm and as soon as i shift and get back on the throttle it starts to break up. i think i might have it too rich in the upper left part of the fuel map and it is dumping too much fuel in when i let off of the throttle during the shift. if i slowly roll onto the throttle it isn't as bad. And yes my BOV is recirculating to before the turbo after the MAF.

It looks like you have the stock vq map with cobra maf.
