Hi everyone. I've read a lot of existing articles but can't find any with my exact issue so hoping someone can help. I recently picked up a 07 335i with the N54. Soon threw a 30FE code so replaced solenoids as a potential fix. The car then threw a 30FF so assumed boost leak. I have replaced some worn looking vacuum lines and checked for any obvious leaks but cannot seem to find any.
After taking some logs it appears the car is only targeting 5-6psi and im only producing 4-5psi even at higher loads 4k+. In gear 3 onwards at higher loads this throws a half EML and a 30FF. Does the car only target what the car can make or is it mapped to target 5-6psi by a previous owner? Any other ideas such as possible lose wastegates?

Im hoping to smoke test this weekend to find out for sure. I occasionally hear wastegate rattle and other times not. Thanks for any help.
