Default Backfire

So I've been having this probalem lately that evreytime I floor my car it makes popping noises like backfiries and the boost goes all over the place. It usually happenes if I just mash the pedal wether it be a rolling WOT or stopped and then go WOT.

Get the ecu scanned for fault codes.

I dont have a VAG com at the moment but there is no CEL, I scanned it with my OBDII and the only code I get is P0422 because I'm running a testpipe. I also noticed it only happens when I hit full boost then it starts to backfire and feel like a surging/stutter

Did you put in non-foulers for your 02 sensor on the test pipe? If you didnt, that could be the reason.

No I didnt do the non-fouler mod to the rear o2 sensor. But this backfire thing just started out of no where...it has me stumped on what it could be.
