Hi all, The turbo blew up after 100k miles, so its been replaced. Since then, around 2.5-3k revs under load there is a squealing noise (similar to balloon having the air released when pinched).
The turbo has been doubly checked, it's fine, so is this one of the many pipes that can't handle the pressure now it has a new turbo? The biggish pipe in-front of the turbo (about 2.5-3" diameter) has also been changed - it still makes the noise. Has anybody else had this and found the cause??

Thanks in adavnce
