It's meant to help, bit won't fully get rid of it.
a split twin turbo pipe(with air guide) should also help.
larger capacity bottom end should help again.
combine all of the above to try and get the best results.
yes, most know the turbos shuffle.
but they do have potential if you have the wallet.
so, keep them, and build it up, ot sell them, and start with something like -5s which are tried and proven.
