freelander td4mtubo whistling

hi
i.m new here and am hoping someone can help
since i changed the maf sensor the car went really well but has started a noise from the turbo, like a loud whistling.
the car now holds back under acceleration
I have changed the intercooler hoses and the one at the rear of the engine seems fine. The egr has been cleaned,
You cant hear it when you rev the car in neutral so anyone whose had this problem before, some advice would be most welcome
cheers

You definetely change all of the intercooler hoses, even the little short one?? Maybe your air intake not quite assembled correctly after changing maf?

Exhaust gasket leaking?

WELCOME!
