Ok, got loads of things to post on this thread, some very interesting techy views on the use of DVs with regards to turbo life, but lets start with a question...

Who HAS damaged their turbo in a way that has led them to belive it was running with no DV that did it? And that damage was actually done?

Il post some tech views about it all in a bit, but if anyone else with decent experience (like Karl etc, or Maybe Mike could ring Harvey n ask his views ) can put forward their experiences (not theory, we all seem to know that) then thatl be cool too...
