Very helpful cheers !!!
LOL.
Revision G holds the most boost.
However, being of diaphragm design can cause them to split prematurely on K03 cars where the DV is bolted straight on to the turbo, especially tuned K03's.
Rev D leak boost but (in my experience) don't completely fail like the Rev G does.
You can also fit a relocation kit, so that the DV is positioned in the engine bay like the K04 models.... woahh almost lost the will to live then...
