If you have an lml and run the h&s dpf delete tunes. Their newest tuner update wil change the turbo vane andl take away that annoyin hiss when you idle if you don't like it. I just done mine today and its sounds a lot better.
It run any cleaner?
Another small negative side effect is the dreaded dead pedal will be a little worse as the turbo takes even longer to spool.
