After fitting an egr delete and fixing a boost leak ( 3inch split ) the car seems to run absolutely fab but I get a rather loud whistle from the turbo ?

Also my engine is rather tappy..almost sounds like an old fiesta ( not related to egr removal)

Any ideas guys? Thanks in advance

loud whistle sounds like another leak lol i had a hole in the pipe from the airbox to the alloy turbo pipe ....

Ill have a look :-)
