Installed JB4 and now getting 30FF

Spoke to Terry and sent him the csv files i have so he could take a look. This seems to happen when i get above the stock psi settings, so even happens on map1. Never happened before the JB4 install so im guessing the increased boost has caused a leak somewhere. Car dont hit boost target at all.

Question is where? Charge pipe has been suggested as the 1st place to look but are there any other known weak areas?
