Why would my car backfire between the 1-2, 2-3 shift with more than 3/4 go pedal depressed. Running 13 pounds boost with 2.5 inch turbo back/ catless exhaust and wrx intercooler.

Backfire out the exhaust?
Also, are you recirculating back into the intake or venting to atmosphere?

Are you sure the BPV is working at all?
When our cars don't recirc like they should the result is that they run very rich especially at 3/4 throttle.
