30ff low boost.

Shortly after some days of replacing my injectors with index 12's , my car has been going into limp mode on wot entering 4th gear. I've replaced all vacuum lines, new boost solenoids but still haven't been able to solve the problem. I do hear the wastegates rattle while deceleration. I also hear some kind of pressure noise while shutting the car off ( only when the hood is opened). What do you think may be causing this? Thanks.

You need to post a log under load, get a full throttle pull in 3rd gear and post it.
