Unhappy overboost + p0420 code

After installing a mr5 box and recharging a k&n filter, the car started boosting easily, like if I just tap the pedal the boost would go up very quick, at WOT it would spike up to 20 psi , on map 1 or 2 on jb4 and then later on I got a p0420 code, what could be the problem? please help, thanks ! maybe it was a coincidence that it all happened at the same time, idk any suggestions will be welcome thanks !
