Hello and welcome

I’d be checking for an air leak on the hoses

As above boost leaks are common, other option would have been leaking injectors as well as a stuck EGR (the latter not so much of an issue but still something to check)

Guys found another problem it goes into limp mode if I got over 2500 rpm could this issue be related?

If it is a split or loose boost hose, it will chuck it into limp.
