Jb4 WOT Issue

[Harrison7140]

Hello everyone, I’m experiencing a slight issue while running jb4 Maps 1 and 2. When I get on the throttle the car will start making a popping sound/misfire coming from the rear/exhaust. I was running the jb4 map 2 just fine for a few months with no issues. Car runs fine 90% of the time on map 0 but occasionally will have the same issue where as running map 1 or 2 will always make this happen. I have Afe intakes, snorkels, aftermarket BOVs, ark secondaries, borla exhaust, ewg wires/pnp adapters and hks plugs gapped properly. I even tried new plugs and still same issue. No codes appearing either.
